[crossfire] Bug tracker group searches

[Kevin Zheng]

Hi there,

Since the bug/feature/patch trackers switched to the new tracker states,
the group searches have been left unchanged. To make these states more
useful, I would like the following searches:

- New (bugs that are "open")
- In progress ("feedback", "analyzed", or "patched")
- Closed (but NOT "suspended")
- Suspended (but NOT "closed")

In addition, the milestones should be updated:
- 1.11 and 1.12 should be closed
- 1.x_next+trunk should be removed
- Add milestones for 1.72.0 and 1.71.1?
- Maybe re-open the "2.x" milestone for really-distant changes?

Somebody with bug tracker modification permissions should make these
changes. The current milestones/searches are meaningless/broken anyways.

Thanks,
Kevin Zheng
