Toggles system rework, added flight pmove mode

- Reworked toggles to use a constant-styled enumerations
- Added TOGGLE_PM_FLIGHT and an according movement mode. Now server-side
  just doesn't simulate gravity altogether for players, instead relying
  on whatever the client provides which works fine for now. Closes #12
