Git: automatically insert issue into git commit message

[bschmalhofer]

The commit message can be prepared via the prepare-commit-msg git hook. See https://git-scm.com/docs/githooks. A suggestion is:

1. When the branch is e.g. named issue-Review code of the migration modules #500-blabla then the commit message is prepended by: Issue Review code of the migration modules #500;
2. When the branch is e.g. name _issue-rotheross/otobo#500-blubber, then the commit message is prepended by: Issue otheross/otobo#500:

The naming convention should enable automatic linking of the commits to the mentioned issue.
The hooks should be installable with the command: bin/otobo.Console.pl Dev::Git::InstallHooks .

Ah, found that input files, e.g. skeletons, are stored in Kernel/System. E.g. Kernel/System/Console/Command/Dev/Code/Generate/ConsoleCommand/ConsoleCommand.pm.skel
TODO:

• move the prepare-commit-msg.dist file
• add the Console command

Let's claim that it works, because it worked once.
