* Replaced the git version comparison mechanism with actual version comparing
* Add notes regarding the git comparison method
Added a simple mechanism to call and compare the user installed git version against the vendored git version, rather than checking if the `git.exe` executable is located in a `/bin` directory.
This fixes false warnings by actually testing if the user installed git is older, or more recent.
Added a small note regarding how the `init.bat` works, and where to put custom `git.exe` binaries as well as where to find the Minified Cmder.
Aliases such as `ls` may have been overridden in the user's profile script and the resulting behavior may be different from `Get-ChildItem`. For example binding `ls` to GNU `ls.exe` generates an error if there are no matching files.
