SourceWebSVN plugin: Allow viewing removed files

Plugin SourceWebSVN : fix wrong comparison of SourceChangeset action field ...

Possible values of this field are:
'add' for file added
'rm' for file remove
'mod' for file modified
'mv' for move

Plugin SourceWebSVN : fix typo

WebSVN plugin : Fix wrong method call

Plugin SourceWebSvn : fix 'compare' parameter (has now format 'path'@'rev')

SourceWebSvn plugin : fix typo

SourceWebSVN plugin : Remove 'sc' parameters from generated links (obsolete)

Remove if / else in url_changeset (The 'comp' operator works for both multiview and non-multiview mode)

WebSVN: refactoring using http_build_query

WebSVN: differentiated URLs depending on multiviews option ...

The plugin is now able to handle both types of WebSVN URLs:

- standard URLs, e.g.
  http://example.com/listing.php?repname=MyRepo&path=%2Ftrunk%2F&rev=10&sc=1
- multiview URLs (introduced with 577ff7e) like
  http://example.com/MyRepo/trunk?&rev=10

This commit restores the WebSVN functionality for sites not using the
multiviews functionality (i.e. as thigs were prior to commit
577ff7e).

Fixes #46

WebSVN: added helper methods to retrieve repo info ...

get_websvn_url, get_websvn_name, get_websvn_path

WebSVN: add is_multiviews method

WebSVN : Add option to handle "Multiview" mode ...

WebSVN can be configured to use Apache Multiview link format [1]. This
commit allows users to specify if this option is enabled or not in the
settings page of their WebSVN repositories.

Note that theses changes only make the option visible in the WebSVN
repos config, but does not alter the plugin's behavior. The next step
is to check the value of this option so the plugin can format WebSVN
links as appropriate.

  ==> use 'sha' instead of 'id'

Bumping version numbers ...

Core framework version -> 0.18

Github: update language strings following fix for #34

Github: Wrong comparison of repository name ...

On Github the repository names are not required to be lowercase. The
repository name send in the payload-data by Github could be something
like 'RePo-SiTory_NamE'.

In that case the comparison will fail and no import is possible.

Fixes #34

Gitweb: Don't use PHP_EOL when parsing output ...

PHP_EOL is valid only for the current instance of PHP, while Gitweb is
perl and potentially running on a different architecture.  Filter CR/LF
explicitly instead.

Fixes #40

WebSVN: fix broken links ...

Prior to this, every link to WebSVN (v.2.3.3) created unrendered
template pages. This changes URLs from 'websvn/action.php?path=&repo='
form to 'websvn/repo/path?op=' form.

Fixes #46

Simplify user-parsing code ...

Function Source_Parse_Users() was simplified by removing nearly
identical code to process the author and committer to a generic function
handling this task for both types of users.

Changesets store author's id instead of committer ...

When a commit is authored by A and committed by B, Source_Parse_Users()
function incorrectly sets A's id instead of B's as the committer,
resulting in incorrect changeset information being stored in the DB.

Fixes #44

Fix whitespace

Add ChangeSet viewer support

Change WebSVN urls

Remove duplicated language string

Remove executable mode from english language file

Fix a number of bugs, support listing files modified ...

Ton Plomp contributed a patch in June 2010 to resolve a bug whereby
automatic additions of changesets were not working. Another bug with
incorrect timezone offsets was also resolved. Finally, Ton's patch also
allows for the author email address to be unspecified on a commit.

In October 2010 Marcel Bennett reviewed Ton's patch and made a few minor
changes/corrections. Marcel has also added the ability for the
SourceHgWeb plugin to retrieve a list of files modified in a commit.

I have modified the patch to escape variables before outputting them so
that this plugin is safe from potential XSS vulnerabilities.

Update HgWeb plugin to work with Source 0.14

New SourceHgWeb plugin for Mercurial integration ...

This plugin is based on the Gitweb plugin as HgWeb/Mercurial are quite
similar to Gitweb/Git. The only missing feature at the moment is the
ability for SourceHgWeb to determine which files were
added/removed/modified with each changeset. The reason is that HgWeb
doesn't give us easy access to this information in the same way Gitweb
does. Hence we will need to manually parse the changeset diff (--- and
+++ lines), checking for /dev/null as a filename in the event of new
files or deleted files.
