[Cin] Bump Autos + other checked into GIT

A short explanation by GG:
Bump autos are a kind of floating point keyframe that differs from the rest
of the floating autos, like smooth, linear..., in that they have two values;
a left and a right edge value.  The presence of a "bumps" creates boundaries
to regions on the timeline.  The region begins at that bump, and extends to
the next bump auto.  If the bump "span" toggle is set, then adjusting the
left/right edge value will raise or lower all of the auto values in the
bump region.  For example, if you put a speed bump in at 1.0 secs and
at 2.0 secs on the timeline, and adjust the right edge of the first auto to
speed 3.0, then the first region of playback (between 0.0 and 1.0 secs) will
play at normal speed, the next region (between the speed bumps) will play
at 3x,
and the last region (after the 2.0, which moved to 1.333 after speed up)
play at normal speed.  Adjusting the "bump" edge values when "span" is on
modifies all of the keyframes between edges of bumps, or to the beginning or
end of media if there are no bumps to end the bump region.  Turn "span" off
if you only want to change the edge value without modifying the region

> Test builds for Ubuntu 20, Mint 18 and Arch can be downloaded (*in about

> look for the one with today's date on it.
> The icon symbols that were checked in are still being worked too.  GG
