Experimental keymap: further tweaks to subdivision level shifting.

The minimum subdivision level is now always zero, and the maximum is
the render subdivision level.  This seems sensible, as it's unlikely
the user will want to shift to a subdivision level higher than the
render level.  It also provides flexibility, so that the user can\
effectively set their own maximum for a given model.

Also, misc tweaks to other parts of the keymap, to make things
function a little more smoothly.

Experimental keymap, bunch of changes/additions:

- Keyframing is now on "K" instead of "I".  This is incomplete, however,
  as it seems "I" is hard-coded for button views (e.g. properties panel,
  etc.).  Need to fix that at some point.

- Keymap for timeline.

- WIP (but mostly done) keymap for nodes.

- WIP keymap for armatures

- Made the translate/rotate/scale hotkeys switch between the
  translate/rotate/scale manipulators if transform manipulators
  are on.  They still behave normally when transform manipulators
  are off.  This may be a terrible idea, but I think it's worth
  trying.  The rationale is that hopefully most users prefer either
  the hotkey OR the manipulator approach to transforms, but not both
  mixed.  That may very well be a wrong assumption, in which case
  we'll need to do something else.  But if it is a right assumption,
  then this provides a really fast way for manipulator users to switch
  between the manipulator types.

- Misc improvements/tweaks to mesh edit hotkeys.

- 'V' is now the hotkey for zoom-border.  Super useful function, and IMO
  deserves prime real-estate.  Loosely related operators "Clip Border"
  and "Render Border" are alt-V and shift-V, respectively.
