New operator for 'splicing' Alembic data, i.e. writing part of the frame
range to a new archive.

This feature is useful when cache size becomes to big and unwieldy.
For sending shots to a render farm a large cache can now be split into
smaller parts, which are spliced off and can be sent individually.

Scrubbing after movie has finished playing works now

Initial support of audio scrubbing in blenderplayer.

Still lots of corner cases to check:

* sound FPS not changing with speed settings of player
* picture and video still not 100% in synch
* Haven't checked what happens when audio is finished.

Some changes were made to make things nicer:

* Scrub now initiates on mouse click instead of mouse motion, makes
things more predictable.
* When scrubbing a movie with sound, don't pause playing after
scrubbing.

Optional arguments for the cache baking operator to chose a frame range.

If these properties are left undefined the operator will use the scene
frame range as before.

Very basic printing of cache bake info to have some feedback in
background mode.

Test support for audio in internal player to showcase in weekly :)

Removed redundant particle matrix calculation when writing hair caches.

This could give a significant improvement in cache baking speed. The
particle matrix is particularly costly to calculate for highly
subdivided meshes.

Fix for Drag force fields: was using inverted velocity.

Zoom to frame options, requested by the Hwoozeberry (dutch translation)
team.

There are 3 options here:

1) Keep range (previous behaviour)
2) Seconds - allows a specified offset in seconds around current frame
3) keyframes - zoom to include a number of keyframes around the cursor

Options 2 and 3 have their own properties to tweak the behaviour and all
options can be found in User Preferences->Interface under the 2D
viewports section.

Number 3 will probably need some refinement so commiting here for the
hwoozeberry team to test first.

Fix for previous commit: the "goal deflect" feature wasn't actually
filtering effectors by type.

Optional feature "Goal Deflect" to disable goal forces when hitting a
deflector object.
