Removed TISCam from build-openspim.sh targets

I didn't realize TISCam was another 'private' DAL -- it has dependencies
in 3rdparty that aren't available to others. Removed from
build-openspim.sh.

Merge branch 'openspim' of git://fiji.sc/micromanager1.4 into openspim
Fixes to openspim.sh

Restored add-desktop-shortcut, had it return 0 on error so the startup
doesn't cancel, had openspim create the JDK directory... etc.
