colorbox 6.x-1.0-beta4

The biggest thing in this beta is a Views Colorbox custom field handler and a easy way for other module like Image Picker to make use of Colorbox.

Changes since DRUPAL-6--1-0-BETA3:

New features:

• #780674: Support for colorbox in imagepicker: Patch by hutch that adds an easy way for other module to make use of Colorbox
• #799216: Views Colorbox custom field handler: Shamelessly stolen from the Lightbox2 issue #474454: Views lightbox2 custom field handler (update).

Misc:

• #789450: IMCE Editor conflict with Colorbox : Added "imce*" as a default excluded path.
• #799190: drush script error - add documentation on requirements: Added a check for "unzip" to the Drush command.
