Fixed a bug and added a feature to the calendar.

The bug I fixed is that my compare function to compare the calendar date to the raid date was comparing the raid date it gmt time so depending on time zone of the server some of the raids were displaying in the wrong dates.

The feature I added is that the calendar now displays the raids in the user's set time zone. So if the server is in pst and the raid is schedule for 11pm, but the user is in est then the raid will display in the next day of the calendar for that user.

Next up is to set a user preference to switch the raids to display in the user's timezone or the raid's timezone.
