Application now detects all valid mountable volumes, not just "removable" ones like USB drives. This means we can now install onto an external HD, for example.
Fixes #25.
Adjusted Document window xib files so resizing looks a lot better.
Don't disable the Install button in the document window if the user selects to install non-present firmware.
Updated Spanish localizations and adjusted some auto layout properties.
Eliminated the Preferences icon from the toolbar to better comply with the "Mac way"; localized title for Modify Boot Settings panel in Spanish.
Added a Localizable.strings file and moved strings from RHAppDelegate.m into that file.
All dialogs and user interface in the main menu screen and preferences dialog are now localized into Spanish.
Update README

Small changes to the description on Enterprise.
Renamed the RHAppDelegate class to AppDelegate.
Merge remote-tracking branch 'Remote/working' into working
Merge conflits in README.
Renamed class RHNotificationViewController to SBNotificationViewController.

Removed un-used project files.
Disabled the make USB and erase USB buttons which are disabled when you start the installation.
The installation window's title now indicates the ISO that you're installing. This allows for better identification in case there are multiple install windows.

Added partial traditional Chinese localization, done by a third party user.
Slight fixes to translation files.
