Fixed --autocrlf option on init so that it will set the autocrlf option
in the config.
Added --ignore case option to set ignorecase config setting.

These changes allow these settings to be controled when creating new repo
with git tfs init

Fixed unit tests to work with new CreateTfsRemote signature
