ugly hack to let us re-map the A and ctrl A keys
support SMPTE as input for 'time' fields when unit is set for the scene

you can do 1h3s4
or using smpte directly 1:0:3:4

More on SMPTE:

force fcurve AUTO handlers to use 1/3 of the distance for smoothness
see: http://www.blender.org/forum/viewtopic.php?p=65508&sid=02e88fe6e3a43338ec8bc354991bc402

Note: this is also used by the curve code. The magic number 2.5614f
comes from review 290361776e5858b3903a83c0cddf722b8340e699
use D instead of X for the official delete operator
support SMPTE display when entering a button
smpte: stripping off leading zeros
Add a time unit 'frame' that does not apply any scaling factor
(values entered in the UI are left unchanged)
Added a B_UNIT_DEF_NOSCALE flag to bypass scaling.
Add parser to remove leading 0 from smtpe (because blender doesn't
understand leading 0)
