Import of the build specs from OBS: the Fedora/SuSE/RHEL6 and xUbuntu 12.10
OBS: recipes for the older Ubuntu versions
OBS: spec for the nightly builds
OBS: looks like "version" is required here
OBS: the new unit tests actually require the X connection
OBS: the nightly version ships without l10n, so silence these RPM errors
OBS: debugging for the Xvfb
OBS: looks like Xvfb from OpenSuSE is broken without xkeyboard-config
OBS: use a different package name
OBS: use the -nightly postfix consistently
XtConnect: change the way how the values are escaped before passing them to PostgreSQL
Update the copyright details for xTuple
OBS: split files into where they belong
OBS: current status of the trojita-nightly as of r33
OBS: fix a syntax error for debian.rules
OBS: looks like they don't support reasonable overrides in there
