init.bat: check for git in path

Browse Source 
The idea is:
* if the users points as to a specific git, use that
* test if a git is in path and if yes, use that
* last, use our vendored git

We don't make any attempt to guess a different location, if a user wants their
own git install, they have to choose "add git to path".

Also check that we have a recent enough version of git (e.g. test for
<GIT>\cmd\git.exe)
