Fix #22, but floating windows mess up ordering.

For reasons that should be obvious.
Merge branch 'develop' into numist/issue-22
Update WindowLevel filter to avoid forward-declaring private API

Because it's pretty brittle to do that.
Sort floating windows to the end of the list, pending fix to #25.

Because it's less annoying than having them at the beginning of the
list.
Fix #21
Fix #26
Merge branch 'numist/issue-22' into develop
Fixes #22
Chrome doesn't respond correctly to -raise, back out fix to #22

Might make it an option, but best not to expose anything that straight
up doesn't work.
Organization and property setter code gen.
Checkpoint, need to sleep.
Merge branch 'develop' into numist/hotkey-refactor
Implement subscription/unsubscription of blocks for meta key combinations.
