Support for git show

[stefanstranger]

I would be great if 'git show' would also be supported by ugit, so that we can get object properties for the different information being returned by git show command.

Sure thing!

Git show might be a little bit of a fun challenge, as it seems like I'll have to reuse some of the other parsers for some scenarios.
