Add a diff window

This allows you to do something like

	gitx --diff

to display a diff similar to 'git diff', but with GitX prettification.

It accepts all git diff parameters, so you can do something like

	gitx --diff HEAD~10

to show the diff compared to the last 10 commits. Or, you can something like

	git diff | gitx

to pipe anything that produces a diff to GitX
