vc-refactoring: The versioncontrol.web_ui modules are now abstract components.

This makes it possible to slightly change their behavior in derived classes
for supporting other SCM backends.

'''Note: this is most probably a temporary situation, if the coming up changes
are propagated to the generic classes, there will be no need for that.'''

Also, the ''Next Changeset'' link is sometimes not existing, even if
the changeset currently shown is not the last one (i.e. end of branch situation).

vc-refactoring: `IScmBackendInterface` and `ScmBackendManager` introduced.

This is similar to what I did for the source:branches/cboos-dev/db-refactoring
so there will be some opportunity for code sharing.

Now there is support for creating a Trac environment without specifying a repository
(see #156).

Also, by specifying the prefix 'direct-svn-fs', one can use the Subversion backend
without the cache, which can be useful for development or if you're annoyed by the
'resync' command...

vc-refactoring: Changeset next/prev navigation links are always both present.

Simply, the next or prev link is inoperant and dimmed out if there's no such changeset.

vc-refactoring: Refactored the revision navigation
* don't cache all existing revisions in the case of a scoped repository
* next_rev and prev_rev use the history, even in the case of a non-scoped
repository, as this does authorization checks
* oldest_rev should be 1, not 0

vc-refactoring: cleanup for the path normalization (even on Windows, "/" is needed)

vc-refactoring: `s/_scoped_path/_path_within_scope/`, which is more correct and removes the ambiguity with `self.scoped_path` which corresponds to the exact opposite

Branching 0.9 to do some VersionControlBackend refactoring

Ported [2457] to 0.9-stable.

Fix ''due'' message for milestones to display the day after the actual due date. Otherwise milestones were due 00:00 at the due date, which is obviously a bit early. Closes #1633.

Ported [2455] to 0.9-stable.
