Assorted bugfixes - Sequencer/Preview Range:

* Snapping strips now works with the hotkey  Shift-S   as in the rest of Blender
* Preview Range works in Sequencer now (the operators for setting, clearing, and also drawing)
* Related to the Preview Range for Sequencer, toggling the time-display mode also works
* Preview Range Set operator now works again, after the modal keymaps change for borderselect broke it. Also sends correct notifiers now after bein called.
