Some very simple modifications

Hello!

I saw your code and liked it a lot. I was looking for something like that.
I made some very small modifications, nothing trivial. Don't know if you like, but I'm creating the request anyway.

I'm also trying to communicate with the bot_jira maintainer in drupal.org to see if he plans to publish anything. If not I'll ask him to give me/us permissions to the module.

Bye,
Bill
