Add a minor (temporary) fix to desktop drawing

I'd rather have the cursor for the desktop texture to show properly than
show up garbled.  I'd rather be spending my time in obs-studio right now
though.  obs-studio will have a built-in way of dealing with
multi-texture based sources much better (rendering to texture)

Bump file version and copyright
Fix FLV writer

The first FLV packet was getting thrown off by initialTimeStamp, because
I foolishly forgot that even if the function was called with 0 as the
argument for the timestamp, it would still subtract the -1 from that.
Also made the capitalization of timestamp to be consistent with other
variable in the file.
