gateone.js:  Some localStorage fallback fixes courtesy of CyberShadoow.
terminal.js:  Fixed JavaScript error for browsers without urlObj support (courtesy CyberShadoow).

authpam.py:  Fixed a bug where Gate One would fail to start due to an exception resulting for a failure to import the gopam.py module.  This should correct the issue reported in #161 (https://github.com/liftoff/GateOne/issues/161) related to OpenBSD support.
