2.5: work on bringing back SpaceTime options

- RMB select, also with SHIFT
- RMB tweak for translate
- SHIFT+D dupli
- BKEY border select/deselect
- AKEY (de)select all
- XKEY delete
- GKEY grab

Added some XXX comments for future todos, especially for when other
spaces come back with time markers.

Also added ED_util for putting in all to-be-cleaned cruft

Context conflict: input methods for Markers can conflict with other
spacetypes. It was solved in pre-2.5 with manually tweaking it all over, 
but I would prefer one keymap for all marker stuff. Needs some thinking... 
could be solved with a boundbox check for bottom part of 2d window.

Tweak issue: both tweak styles are possible:
- Hold mouse button, move, operator ends on mouse release
- Hold mouse button, move, operator ends on mouse click

Problem is that modally handled operators use fixed keymaps... like ESC,
SPACE, ENTER, or press/release mousebutton for 'assign'. There's a lot 
to say for making this all consistant, or become part of 1 general keymap?
Should also be possibe to define 'tweak' defaults for Tablet different 
than for mouse...
