Stella SVN r2291

Stella SVN r2291 is released. Stella is a multi-platform Atari 2600 VCS emulator. The Atari 2600 Video Computer System (VCS), introduced in 1977, was the most popular home video game system of the early 1980's. Now you can enjoy all of your favorite Atari 2600 games on your PC thanks to Stella!

Stella SVN changelog:
r2291
The sound system is now opened once per program invocation, and paused
when it isn't needed. According to SDL this shouldn't be necessary, but
some combinations of video modes and audio hardware cause sound to stop
working if it's repeatedly opened and closed. So we have to keep it open.

Always attempt to use 2 channels (aka stereo) when opening the SDL audio
device. This is now required, since ROMs can request mono or stereo mode,
and the sound system can no longer be closed and re-opened with the
desired settings. So we need to always use 2 channels to accommodate
when it might be needed. This actually more closely emulates the 2600,
which does have two audio channels. The 'mono' vs 'stereo' ROM property
basically controls whether these channels are exposed (ie, does the
virtual console have two-channel audio hardware installed). In that sense,
these settings control how the channels are mixed.

Updated some settings to have more reasonable defaults.

Added acknowledgement for people that have donated hardware to help with
development.
