Added various updates for issue creation:

@mgan59 @evankline @CoreyTrombley - Last night I decided to scratch my itch with this tool.  I've got another couple of PRs coming down for it shortly as well.  This PR adds the following functionality to the issue creation:

* Ask to create another issue
* Optionally Set assignee
* Take title as description if left blank
* Optionally take Proj-Issue as command line arg

** When merging in, please do not delete this branch!**
