[dev] Adding conflict checking to kronolith

[Jason Rust]

We use kronolith as a calendar for keeping track of who is using what 
conference room.  However, there are some users who don't bother to check if 
a room is already reserved before making their reservation thus causing 
double-bookings.  To resolve this issue we are thinking of adding conflict 
checking to kronolith.  I am in the beginning stages of working out how it 
would work, but the two major changes I see happening would be:
1. Location would become a select box (only in this mode) instead of a text 
box so as to ensure that a room could be uniquely identified.  The list of 
locations would be a pref.
2. Before the event is added it would check to make sure that an event with 
the same location is not occuring during the requested time (only in this 
mode).

I have a couple questions.  Would the kronolith team be interested in 
implementing this into the app if I write it?  Would this be duplicating 
someone else's effort (i.e. does a feature like this already exist either in 
kronolith or one of the other apps)?
