This should fix [#31801] "OBJ importer doesn't import smoothing groups as sharp edges" reported by Tom Penn.

There was code to mark edges as sharp but it was disabled as being too slow. Found a quicker way using bmesh.

Now the importer assigns the object the same name as the object data.

This should fix [#31835] "OBJ Importer corrupts a model (crash in edit mode)" reported by paul geraskin.

The importer did the mesh validation before calculating edges (should be the other way around).

Code generating frame range was buggy...

Elapsed Time off by default, and little fix in positioning.

=====================

While doing some tutorials, realized that when working fullscreen you often lose perception in how much time passed, resulting in unnecessarily long videos.

To tackle this, today I implemented a 'Elapsed Time' feature, with options for color/alpha, size, and reset (to restart the timer without restarting the script).


Thanks to Campbell Barton for guidance, ideas, and just being awesome.

- Noticed in some tests[1] that when speeding up even just 2x the maximum fade time felt small, increased max to 10 (but kept softmax as 5)

=====================

- Use Shift + Alt + C to start display
- Panel was getting big, now only show options if it is actually displaying something
- Updated Wiki link and bumped version to 1.7
- Little changes here and there

=====================

Some improvements and fixes:

- Fade Out Time - option to specify (in seconds) how long until the key event disappears
- Mouse icon can be on left or right, regardless if Display Box is On or not
- Display Last Operator doesn't rely on whether in box mode or not 

====================
Updated some parts and added some new options:

- Individual color (and alpha support) for text/icon and background box
- Shadows on text for better readability
- Display Last Operator option when box is active
- Background Box is now always drawn (less noise)
- Option to hide the box when no key is pressed and change its width
- Text is drawn on top of the box (used to be below)
- Reshuffled the UI a bit

This is my first commit on this addon, so any feedback is very welcome.
A lot more work is needed in this area we know, but I think in the meantime the changes so far make this addon much more flexible.

Mhx importer. Rigs other than the mhx rig can now access the MHX Drivers panel. Drivers for facial shapes are located there.

1. There was a bug when separating a single ball from a dupliverts
structure upon pushing the button "Separate atom" in the Atomic Blender
panel. 

2. Thanks to an inspirations from <CoDEmanX> I changed the code such that 
all selected atoms (vertices) in the "Edit Mode" are seperated at once.

IMPORTANT: I plan on deleting Rotobezier script as soon as we got the new masking tools in Trunk. However since animating curves is still useful for non masking tasks I've:

- Ported Curve animation features from Rotobezier addon to Animall. Rotobezier animated files should be compatible with AnimAll. Left the masking specific features out though.
- Fixed Vertex Color animation for new API
- Updated UVs to new API, however this still doesn't work because of bug #31631
- Vertex Groups also don't work because of bug #31632, however code still looked alright.

Some cosmetics ...
