Duplicate session warning upon session submission

[adrianbanks]

Triggered by this. When submitting a session, it would be nice to know if someone else has already submitted a similar session (the heuristics of this "similar" will need some thought).

Wow, what are the chances of two people picking the same title for a talk??

If the title is 'CQRS From The Trenches' then chances are pretty high - John Nolan in Manchester was pondering submitting a third talk with that title last week, until it was pointed out there were already two. Stack suggested a check for similar titles in the code - or, more accurately, in his arsey way he bemoaned the lack of a check.

And someone else mentioned to me the same title in a completely unrelated context last night 😄 What is it with that phrase?!
