[orca-list] Heads-up: I've branched for 3.14 and please test master

[Joanmarie Diggs <jdiggs igalia com>]

Hey guys.

I've been working and working and working on the Gecko support rewrite.
All the sad hacks have been rather difficult to untangle. So in order to
balance heading towards stability for the approaching 3.14 release
whilst making progress on the rewrite, I've just done two things:

* Branched for 3.14
* Committed some work-in-progress caret navigation support to master

I want to stress work-in-progress. There are undoubtedly many bugs. And
I'm far from finished. But... Word navigation should be largely (if not
entirely fixed). Line navigation should work better and be more
performant. Question is, are the improvements significantly better than
any regressions I may have introduced? From my testing so far, yes. But
before I consider putting those changes back to the 3.14 branch, I'd
love it if some of you could hammer on it and let me know. In the
meantime, I'll keep working on the rewrite. And I'll delay rolling the
3.13.91 release until tomorrow evening.

Please let me know what you find. Thanks in advance!
