Direct all BlockPlaceEvents to a singular location. Fixes BUKKIT-3438

By having a single function to process BlockPlacement logic, we make
it so that there is consistent behavior throughout all BlockPlace
events. This should allow for easier troubleshooting and less diffs
in source.

This also fixes BUKKIT-3463 by including the correct coordinates that
were clicked to the event.
