[orca-list] Branched for 3.20; committed part of keyboard event refactor

[Joanmarie Diggs <jdiggs igalia com>]

Hey all.

Subject pretty much says it all. The active stable branch of Orca is now
the "gnome-3-20" branch. Master is now unstable in all senses of the
word. I will try not to break things, but if you must have a reliable,
stable version of Orca at all times, you might wish to not use master
until we get further along in the 3.21 release cycle.

Pavel: I just committed part of the keyboard event refactor I'm doing.
If you are still having problems with 3.20, please try to reproduce the
problem using Orca master and send me (privately) a full debug.out. Thanks!
