JSLint. RFB obj to rfb.js; vnc.js the 'loader'.

Move the whole RFB object to rfb.js. vnc.js is now just the loader
file. This allows an integrating project to easily replace vnc.js with
an alternate loader mechanism (or just do it directly in the html
file). Thanks for the idea primalmotion (http://github.com/primalmotion).

Also, JSLint the various files.
