Add two events that are fired when a player is denied building, and when a player builds.

TownDenyBuildEvent - if canceled, allow building
TownBuildEvent - if canceled, deny building

Would be helpful for plugins. 😄

Another nice idea, but perhaps different names?

TownDeniedBuildEvent - if canceled, allow building (place, break, fill, or empty)
TownAllowedBuildEvent - if canceled, deny building (place, break, fill, or empty)

Not 100% sure on this, I'll have a closer look tonight and comment again.

Sounds good!
