Features:

1. Added a new config item to prevent spawning off map entities (also toggleable feature to automatically refund if DarkRP and bought from F4 menu)

Changes:

2. Disable EntityLimits if 'Enable Spawning Restrictions' is turned off.

Fixes:

1. Setting entity limits to -2 not always applying properly.
