[MozillaBugTrackerBridge] New Bridge

[AntoineTurmel]

This Bridge is a clone of KernelBugTrackerBridge (thanks to @logmanoriginal) but for Mozilla Bugzilla. There is some difference in the class used to get the right comments.

BTW there is a bug opened in Bugzilla to support RSS feed ^^ see: https://bugzilla.mozilla.org/256718

Thanks for the PR!

From what I can tell the differences between bugzilla.kernel.org and bugzilla.mozilla.org are very little, only favicon and some classes on line 69. I think it makes sense to merge them into one BugzillaBridge, right?

Especially because there are lots of sites using it: https://www.bugzilla.org/installation-list/

Yeah I was thinking of doing a generic Bugzilla bridge, but there can be some changes in some installations... maybe we can do a Switch inside the bridge to handle specific installations ? I'll see if I can make more Bugzilla instances to work.

I did something similar in the XenForo bridge, where different versions are detected based on certain classes found in the DOM. Not the best solution, but unless the version is explicitly included in the DOM this is one way to go. I randomly used VERSION_1 and VERSION_2 for whatever class I found first 🤷‍♂️

bugzilla.mozilla.org fortunately has the generator tag included in the header. It indicates the specific version used (currently Bugzilla 20181106.1).

bugzilla.kernel.org unfortunately doesn't 🤦‍♂️

One way is to check if the version is specified and act on it. For trackers without explicit versions we can just search for some class and assign random versions. Of course, if the generator has an unknown version, we got a nice way to notify users to report it, so we can add the new version.

Merged. We can combine bridges at a later time, when it becomes a bigger concern. For now it I think this works fine.
