The (B) and (Z) models listed at
http://support.apple.com/kb/HT2841?viewlocale=en_GB have these keys

the Keys prefs fields.
Use sRGB when changing color palette
Add atom editor and clean up trouter code

Merge branch 'master' of https://github.com/gnachman/iTerm2
Add atom editor and clean up trouter code
Clean up header file
Rename trouter everywhere except in prefs
Rename trouter prefs to semantic history prefs
Rename the last trouters
resolve merge conflicts
Finish writing tests and cleaning up
Don't wait for sublime text, etc., to finish running when launched from semantic history
Allow cmd-opt-shift drag to move a window if a session is dropped on itself, so long as there are no split panes in the current tab.
Sort includes in MovePaneController
Fix a bug where device status reports would be affected by broadcasting input. Issue 3329
Add tests for semantic history handling filenames with parens and line numbers
Don't require cmd to be pressed to drag a selection or an image (but it's still allowed, seems harmless).
Force divider color to be light gray. Apparently it's clear by default which makes fullscreen tmux look bad against black sessions (issue 3336).
