Searching for bug tickets (extending the Jira search goodie)

Hi, this is an answer to the following idea: https://duckduckhack.uservoice.com/forums/5168-ideas-for-duckduckgo-instant-answer-plugins/suggestions/3424035-direct-support-for-debian-and-other-free-software-

I updated the Jira.pm class which returns results for Apache and Codehaus bug tickets. Now it is called Bugtracker.pm and support searches for the Mozilla, Eclipse, LibreOffice, Linux kernel and Debian bug trackers.
I also fixed a few minor things in the code.

I haven't found any efficient way to support github or launchpad projects bug trackers yet (the main difficulty is crafting the URL to return in the answer box without asking to much information from the user search input). 
But other specific bugtrackers should be easily added to the goodie.

Looking forward your feedback!
