commands in base plugin with flags.
- Use standard execution log entries in all VCS plugins (outputwindow).

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

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()).

Run git as a cmd.exe subprocess as a workaround. In the long term
we should look into enabling QProcess to properly handle .bat and
.cmd files.

Do not check for existence of the binary, breaks on Windows
due to .exe (and potentially paths). Use waitForStarted().
On this occasion, kill on timeout in case of password prompts.

..in an attempt to suppress password prompts.

Task:     248067
Details:  Use --no-color where appropriate. Use a hack to remove color sequences from output for "status" since it does not support the option as of git 1.6.2.

Make the git plugin look for the binary in the path specified in the settings. Previously, the environment was passed to the process, but that did not affect the location of the binary.

RevBy:    tba
Details:  - as on windows some git commands take much longer it happens fairly often, that git timeouts.
          - added a timeout value to the option to let the user choose maximum timeout value (minimum is 10 seconds, maximum 5 minutes)

replace ExtensionSystem::PluginManager::instance()->getObject<Core::ICore>() by Core::ICore::instance()

forward declaration is sufficient.

Details: Refactor the git command to be able to run a batch. Run diff and diff --cached in a batch
