0.3.0-rc.1

First release candidate for 0.3.0.

Note: This release introduced a BC break as it changed the event name formats (core and plugins) and the core item event names:

• Changes the format from event.plugin to plugin:event (e.g. create.jcarousel to jcarousel:create)
• Removes the item prefix from the item events (e.g. itemfirstin to firstin)

See the events documentation.
