Check for timezone inconsistancy

[Helge Sverre Hessevik Liseth]

Since the calendar dates and times are javascript, i assume they default to the current user's machine, however, the timezone information is not saved when the events are saved, so it is parsed in the timezone of wordpress, this could potentially break stuff.

not sure if the DateTime class parses timezone info and "syncs" it properly, but maybe we should also save the Timezone info with the events.

Timezones are now passed along with the start & end date, its parsed by the PHP and the timezone sync magic stuff is being done
