Mono Repo Support for roomodes

[rawkode]

I have my "dev team" in a .roomodes file in the root of my mono-repo. This works fine if I open everything, but it's a PITA to actually get any work done; so I prefer to open individual services.

Unfortunately, my .roomodes then isn't picked up.

In the event that the directory opened is a Git repository, it would be nice if it checked the directory first, then worked its way up to the Git root, looking for .roomodes.
