wip - fixing cli args being ignored on 10.7

[jdelStrother]

Hi,

I seemed to be having problems with gitx as run from the command line, where the app would just ignore any arguments passed to it.

In -[PBGitRepository showWindows], the currentAppleEvent is nil - I think due to Lion's block-based opening of NSDocuments.

I've got a potential fix at jdelStrother@cli_args, but haven't submitted it as a pull request since it probably breaks 10.6's cli-argument-handling, and I don't have 10.6 around to test on. WDYT?

I also had a fix in progress at datalogics-kam@cea5c4f if you'd like to compare.
