- big cleanup and refactoring in progress for all connectors & file managment related features
 * saving and loading to/from localstorage (browserConnector) finally works again, but a few bugs to fix and cleanup to do
 * a few minor cleanups in dropbox connector
 * modified the way the "dirty" flag in projects works: it is now a backbone type attribute, but accessible via dotted acces see buildproperties module)
 * this was added for more clarity and to have "asterisk" displayed beside the dirtied/modified file names
 * to achieve the above, backbone.modelbinder is now used in the filesTreeview: small amount of refactoring and template changes related to that
 * also added display of connected/disconnected to each connector in the projectBrowserView2 (just a "fork") of the old one
 * cleaned up various modal related stuff in the projectBrowserView
