COMPATIBILITY NOTE:  As of this commit Gate One now requires Tornado 4.0+.  See below for details why (if you care).
applications/terminal/app_terminal.py:  Got rid of the `term_log` global (it was mostly used in a few places and most of the time `self.term_log` would be better).
applications/terminal/policy.py:  Removed the unused `term_log` global.
core/configuration.py:  Added 'version' to the list of settings that should never end up in any *.conf file.
core/server.py:  Added a check for Solaris to ensure we don't try to automatically restart the Gate One process because--for whatever reason--that doesn't work properly on Solaris.
core/server.py:  Gate One now uses the check_origin() function built into Tornado 4.0+.  This means that you need Tornado 4.0+ to use Gate One now.  It's a better/faster method so it's worthwhile.
