Separate remote import page from user imports ...

Due to complexities of trying to have both user-initiated imports and
remote imports handled in the same page, the import process has been
split into two separate use cases.  pages/import.php is now specifically
for use by the remote import process, while pages/repo_import_latest.php
remains for usage by authenticated MantisBT users.

This will require that all cronjobs or post-commit hooks that triggered
a remote import be updated to point to the new import url.  Framework
version has been bumped accordingly.

Require base SVN plugin for SFSVN/WebSVN ...

Due to the fact that both plugins need to ensure that the base SourceSVN
plugin class is available, and to make sure the base configuration
options are registered, the SourceSVN plugin needs to be installed.

Re-licensed the project under the MIT license

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.

Fix #92: Unable to set SVN path on Windows ...

Refactored SVN binary/path validation into a separate function, and use
the new validation routines from the existing API and page code.
