versioncontrol_cvs 5.x-2.0-rc2

Despite being an -rc2, there have been a good number of improvements since -rc1.

• Recording commit information from 'cvs log' (a.k.a. log fetching) was broken in the previous release, that's fixed in this one.
• The CVS backend now supports basic repository browsing via Repoview, though only for the latest revisions on HEAD.
• A cvs.module compatibility layer (implemented as optional add-on module) has been added, so that the 'cvs' menu path (e.g. "http://drupal.org/cvs") keeps working when upgrading from cvs.module. Granted, without the update script being finished this will be of limited value, but we'll need that compatibility layer for Drupal 6 anyways, so why not add it now.
• On the coding side, lots of refactoring has been done, splitting out the code interfacing with CVS into a Drupal-agnostic helper library (which also means it won't need to be ported).
