[KernelBugTracker] Add new bridge
This adds a bridge for bugzilla.kernel.org to provide feeds for bug comments without the need of registering an email address. This implementation makes use of the print preview feature that reduces bandwidth by a small margin. Provides options to specify the number of comments to return as well as the sorting order (latest first or oldest first)
