creativecommons 6.x-1.0-beta1

The following changes have been made since development began for DRUPAL-6--1:

• task #157530, #143956 by balleyne: updated CC API calls to 1.5, now using latest licenses (e.g. 3.0)
• task #157530 by balleyne: changed available licenses to work by license type, instead of class
• Switched to API simple license chooser from API questions interface
• task #157530 by balleyne: switched node license display from hook_view() to hook_block()
• task #157530 by balleyne: changed storage method to license uri instead of serialized object
• task #157530 by balleyne: implemented site license with hook_block() instead of hook_footer()
• task #157530 #516154 by balleyne: fixed content type restrictions feature, added admin overview page for managing setting for all content types in one place
• Distinction between 'All Rights Reserved' and 'None' collapsed (i.e. "None (All Rights Reserved)" -- same thing, like Flickr)
• Option to require a mandatory license removed in favour of including "None" in the "Available Types" selection (i.e. in order to make a license mandatory, simply make 'None' unavailable)
• Support for CC0 implemented -- hard-coded (since it's not supported by the API yet)
• Rather than select a default license, an admin can select a default license type and a default jurisdiction, and the default license is then determined based on that.
• task by balleyne: added warning if selected/default license is no longer available when license selection form is called
• task #157530 by balleyne: implemented hook_perm for attaching licenses
• Added a series of checks for license selection changes: warnings when jurisdiction or version number changes, warnings when license is no longer available
