add pub location warning pop-up

[stevecameron]

Changing the verbiage on the "No pubs found" pop up won't work. There needs to be a new pop-up on the create pub page where the new pub name is entered.

What if there are pubs in the area - and a patron wants to add a new pub they have found in the same area. They must be informed then and there they must be on premiises or we will have the same situation as before - a patron will add a pub and the location will be wrong

@scloune We will take care of the pop up Steve is talking about in the next version.
