Backward Compatibilty Breaks:
Minimum subversion version is 1.4.
svn_status call arguments have changed - it now uses Flags.

New Constants:

SVN_REVISION_INITIAL
SVN_REVISION_HEAD
SVN_REVISION_BASE
SVN_REVISION_COMMITTED
SVN_REVISION_PREV

SVN_NON_RECURSIVE
SVN_DISCOVER_CHANGED_PATHS
SVN_OMIT_MESSAGES
SVN_STOP_ON_COPY
SVN_ALL
SVN_SHOW_UPDATES
SVN_NO_IGNORE

All constants are also available as Svn::REVISON_HEAD.

Most functions have been fixed to work with Win32 paths.
