Add EventShareVideo component to facilitate sharing event video at a time point.
The user can enter a time point input in two formats.
Just a number in seconds.
or hh:mm:ss hh is optional
Also supports something like 1::, which becomes 1:00:00 and :5 becomes 0:05
Any non-digit char (except : and .) is not allowed. Negative numbers are not allowed. These results in an INVALID TIME POINT msg.
The Start at checkbox is used to determine if the time point (in seconds) is added to video share URL.
Change the searchQuery parameter in event page URL to use ?q={searchQuery} as I didn't want to add the searchQuery to the video share URL at a time point.
