gateone.js:  Added a new table builder function:  `GateOne.Visual.table()`.  I put it together so I'd have an easy way to draw tables then update them later.
gateone.js:  Added some type-checking functions go `GateOne.Utils`:  `isString`, `isFunction()`, and `isBool()` (needed them for the new table function).
gateone.py:  Added a new feature:  If you place any static JS or CSS files in 'gateone/static/extra' they will automatically be sent to clients, minified, cached, and kept in-sync as part of the "go:authenticate" event.  This should allow applications embedding Gate One to take advantage of Gate One's advanced JS/CSS minification/cache/sync mechanism for anything and everything.
