Fix clear, start of NormalWorld /w roads

- Updated Metrics
- Fixed not being able to use commands that cost $0 when you have $0
- Fixed removing players from Allowed list when selling plot

cleared instead of the whole server
- Plot Clearing now removes LWC protections from an Asynchronous task
- Properly setting to null every static variables when plugin is
disabled (fix memory leaks)

Fix plotlimit, border protect, WE optimisation

- Fixed the plot limit to default to 1 plot if no limit is set, and to 0
if no plotme permissions
- Removed lag caused by move listener that sets the WE mask
- Added protection to the plot border against people doubling the
blocks.
piston small changes
Added deny

- Added an option to deny players from entering a plot. If you deny
someone currently in the plot, they get teleported to the plot home.
-- Added prices to deny and undeny players
-- There is a global configuration to enable or disable this feature
(allowDeny)
-- Deny * to deny everyone except people allowed on the plot
-- Adds a new table to the database plotmeDenied
- Added permission node to bypass denial plotme.admin.bypassdeny
- Added permission node to build anywhere like what plotme.admin gave:
plotme.admin.buildanywhere
- Added permission nodes to bypass the protected blocks with
plotme.unblock.<id>. Ex: plotme.unblock.54
