OBS: You'll need to resync/rebuild your database!

- This implements an updated, clearer and more robust access system. The policy is now to lock that which is not explicitly left open.
- Permission strings -> Lock strings. Separating permissions and locks makes more sense security-wise
- No more permissiongroup table; permissions instead use a simple tuple PERMISSIONS_HIERARCHY to define an access hierarchy
- Cleaner lock-definition syntax, all based on function calls.
- New objects/players/channels get a default security policy during creation (set through typeclass)

As part of rebuilding and testing the new lock/permission system I got into testing and debugging several other systems, fixing some
outstanding issues:
- @reload now fully updates the database asynchronously. No need to reboot server when changing cmdsets
- Dozens of new test suites added for about 30 commands so far
- Help for channels made more clever and informative.
