In cases where binary 'wish' is not in PATH variable this could not be
started.

Make GitClient::synchronousGit use the process environment.

Windows: Add a setting to fake a 'HOME' environment variable
(%HOMEDRIVE%%HOMEPATH%) to make msysgit look for its SSH-keys
there not only when run from git bash, but also from Qt Creator.
Useful in MinGw-setups, where git must not be in the path.

We now support renaming files. The version control system tries first to
rename, if that doesn't support or can't rename the file we do a normal
rename. (Note: git, hg, perforce > 2009.02 support renaming, cvs not.
(perforce untested)). We correctly notify all editors of the renamed
file and tell the project manager to rename the file in the project.

Note: Only the qt4projectmanager knows how to rename files.

Note: renaming folders, moving files to different folders, renaming
.pro/.pri files is not supported. Those things can be later added after
this has proven to work correctly in the simple case.

Also we don't do any actions based on the renaming like renaming
classes, changing include guards or #include lines.

Do not listen on ICore::contextChanged to update actions
(became slow after additional contexts).
git: Make code to find top level faster, avoid
constructing file info lists.

Modify CodePaster::fetch to do a mimetype detection on the
content, create a filename with the matching extension and
open that file.
This gives correct syntax highlighting  and makes "Save as"
more convenient. Keep the file around and delete on exit.

Modify patch mimetype with some content detection (higher priority
than C++).

Add a "current patch file" to the VCSBasePlugin::State. Add "Apply
patch" to git with whitespace fix.

Do 'git rebase --abort' if something fails.

Create actions with convenient factory functions, do enabling per
file/project/repository centrally.

Present user with a checkable list of files to be cleaned (add reusable
dialog to VCSBase module).

Introduce static utilities to Utils::SynchronousProcess
for synchronous processes that mimicks the handling
of Utils::SynchronousProcess (apply timeout after no
more data are available on stdout/stderr as opposed
to waitForFinished()).

Display correct warning if git is not installed.
Do not display it as error (popping up the log pane) from
IVersionControl.  Introduce separate caching flag to avoid
repeated execution if git is not installed.

Implement IVersionControl::vcsAdd() using --intent-to-add with a cached
version check. On this occasion, implement vcsDelete() as well using
'git rm -f'.

Give dialogs a consistent look, set
WA_DeleteOnClose on them and improve updating.
Add a Refresh/Diff buttons to branch dialog.

Add non-modal stash management dialog and additional menu option
"Stash snapshot..." to stash away changes prompting for a description,
which will immediately replay the stash (take snapshot and continue
working).
Add interface to IVersionControl for creating/restoring/deleting
snapshots for backup/complex undo operations (currently supported
by git only). Add test options to VCSBasePlugin.
Clean up and extend git client accordingly.
