Added MediaBrowserVC, updated copyright notice.

The media browser is just the camera picker with different enumeration choice right now.
Need to add another stage in the alert process to ask the user whether they want to start a new
palette or add to an old one.
Copyright notice on all files updated to include Kevin.
Fixed the thumbnails loading on the PaletteTVC and changed the color of the navBar.
A rollback commit before I start experimenting with ImagePickerController stuff.
Major update to a number of systems.

Updated db uniqueness verifier for palettes.
Added palette selection from Media Browser.
Updated ColorEditor with colored sliders and hidden alpha.
Updated ColorTVC to show hex values.
Tweaked animation in CameraController.
Got thumbnails working in PaletteTVC.
Regrouped files in the project.

Merging Kevin's work into the ManagerDev
Added keyboard helper and better DB verification.

DB: Fixed up the database functions for Colors to have uniqueness verification.  Colors can
now only be created by assigning them to a palette.  Made the MOC into a Main Thread concurrency
(may want to change this, although I don't see us doing any large database operations that would
 require forking off a thread).
Keyboard Helper: From a stack overflow post linked in the CTKeyboardHandler comments.
Removed redundant code and added explicit typecasts.

Removed nonessential NSLogs and some redundant/repetitive code.  Added some explicit type casts between
equivalent enum types.
