- added possibility of creating screenshots of the current 3d scene (very basic)
- more work done on project management:
* very basic and awfully hackish, but saving to dropbox & localstorage both work
* still issues with the fact that a project actually represents a folder + metadata
* for now there are still too big discrepancies between the way localstorage & dropbox backbone plugins handle things

- modified modalRegion & related css for extra size
