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.

Fix #97: Refacter core SVN into shared codebase ...

Created base SVN plugin with the shared SVN code from WebSVN and SFSVN
plugins, and then modified the previous plugins to inherit from the new
base plugin.  This will end the previous need to constantly replicate
changes between the two SVN plugins.

Currently, the only way to modify shared SVN configuration is to have
the base SVN plugin installed, but this is a task for a different
commit.
