vcalendar patch

Attempt at fixing time zone stuff in vcalendar meeting requests.
I have tested it against couple of meeting requests at work. The
requests have originated in different parts of the world and all
seem to display fine.

Note that this patch does not handle daylight saving time stuff.
I have one recuring meeting request that was created while DST
was in effect and it displays fine on winter time (it was created
in my local time zone however so no guarantees it might work for
all meeting requests).

The patch performs the following tasks:
1. Extract UTC offset from the meeting request
2. Convert the event time to UTC time by substracting the offset from step 1.
3. Calculate UTC offset for local time zone
4. Conver the event time from UTC time to local time by adding the UTC offset
from step 3.
