Replaced the ' - ' string with the $area_room_separator config variable
Fixed import so that it works with latest changes (but multiple rooms in a LOCATION property not yet supported)
Restructured code
Made import accept multiple rooms in the LOCATION property
Reverted some code not yet ready to be committed
Added the ability to specify default room(s) for an event when importing an event with no LOCATION property.
Made multiple select boxes resizable
Use jquery-ui-multiselect-widget for selecting rooms in edit_entry

TODO: The alignment of the select box could be improved.
Fixed a bug resulting in an infinite loop when importing a monthly repeat when the BYDAY value includes a numeric value eg "2MO".
