Lot Flags + PVP allowed in Lots (Read Desc)

Done quite a bit,
Added a new argument check for the Lot command to check for /lot flag -
Done some flag checking bla bla.
Set up a flag for PVP, If true will let you pvp (changed listeners to
allow pvp if the flag is there) Done some work with the database to
save and read from. updateLot is now a thing but is currently only set
up to update the pvp flag.
If you want to add flags in the future then add it to the updateLot
part of db, call it on startup and add it to the flag system I have
made.

For this to work the database needs to be changed slightly with:
flag_pvp (as name)
enum('0','1') as type
and 0 as the default.
