When cloning a repository, Stash doesn't preserve case of repository

When cloning a repository, Stash doesn't preserve the case of the repository name in the clone URL.

Steps to reproduce:

1. Create a repository that is case-sensitive, eg "WoosterKit".
2. Select Clone > SSH, copy URL.
3. URL will end with lowercase module name: eg "woosterkit.git"

Now, when you check out this repo, or add it as a submodule, it will have the incorrect case. This is especially unfortunate for submodules.
