Webcal names are not corrected.

[michaellindahl]

Calendar names are properly displayed in the legend but they are not properly displayed in the pick multiple area (they are displayed via their filename).

On line 182 of calendar_functions.php external calendars are simply named by their file name. When the calendar is parsed this should be corrected in the 'X-WR-CALNAME' case on line 414 of ical_parser.php. In this case $actual_calname is properly saved and used for the legend, however the $cal_displaynames is not being saved properly as according to what I have seen $cal_displaynames does not refer to anything.
