- Use standard execution log entries in all VCS plugins (outputwindow).

Merge managesDirectory() and findTopLevelForDirectory()
into one giving managesDirectory() an optional topLevel
parameter. This removes the need to go up the directory
hierarchy twice when checking for Merurial or git and also
saves some checks for CVS/Subversion.
VCSManager: Check cache in reverse order starting out with
the full path first to improve handling of nested repositories.

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.

Some categories do not have icons yet, unfortunately.

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.

Static leaks, but causes noise in valgrind output. :)
