Dialog boxes almost complete

Fixed validation for user name to allow caps/spaces
Removed private key validation until one can be created
Animate dialogs
Added label to display selected friend underneath button
Correctly destroy dialogs when done with them

Added ragingdipsticks specific class for bootstrap, so the bootstrap format does not mess with the page
NOTE: it is not currently being used, replace css/bootstrap.min.css with css/bootstrap_rgdpstks.css to see the difference. However it is not themed like David's bootstrap. I need to get with him to format it.

Removed tester methods from background.js
