gateone: Updated to version 1.2

gateone: Updated to version 1.2

This new version of Gate One uses a new configuration file format which
means the old server.conf is gone.  It now stores configuration files in
/etc/gateone/conf.d.  The /opt/gateone directory is also gone and
instead the package installs like a regular Python module in
site-packages.  SSL certificates/keys are stored in /etc/gateone/ssl/.

The new version requires python-tornado 3.1.1 (which was submitted
earlier today) and the python-futures package (which was also submitted
today).

An 80oe.conf file has been added specific to OpenEmbedded that replaces
the old pre-configured server.conf functionality.

The old patch that removes the init script checks has been deprecated by
the use of the --skip_init_scripts option which is now being passed to
setup.py.

Lastly, Gate One 1.2 is about twice as fast (benchmarked) as Gate One
1.1 on the Beaglebone platform.
