Add support for self referencing submodules

When working with relative submodule paths, The "./" needs special
handling similar to "../".

See information on:
https://git-scm.com/docs/git-submodule
Which currently states:
"<repository> is the URL of the new submodule’s origin repository.
This may be either an absolute URL, or (if it begins with ./ or ../),
the location relative to the superproject’s default remote
repository (Please note that to specify a repository foo.git which is
located right next to a superproject bar.git, you’ll have to use
../foo.git instead of ./foo.git - as one might expect when following
the rules for relative URLs - because the evaluation of relative URLs
in Git is identical to that of relative directories)."

The implementation also was not handling file/directory names
starting with "." or "..". Explicitly look for "./" and "../"
instead.
