Some Anticheat restructuring and new features.

* Renamed get_power() and moved to common.py
* Added anticheatpackage/constants.py and moved all anticheat related constants there
* Fixed bug in log, where I was comparing loglevel the wrong way around, derp!
+ Added glider reset attack animation bug abuse detection
+ Added equipped consumable checking
+ Added checking for the ranger stealth flag on none rangers

NOTE: New checks will not work until matpow2 adds on_consumable_update and on_flags_update events. (They are tested and work, however.)
NOTE2: Requires "scripts" directory to be added to sys.path or PYTHONPATH locally.
