Fixed spawning guns near spectators

Randomisation performance improvements and code cleanup

Added new convar: ttt_floor_weapons_spawner_near 4
Number of guns to spawn near players that don't have a gun near them when everyone respawns for the next round

ttt_floor_weapons_spawner_limit is now 300 by default, down from 350

ttt_floor_weapons_spawner_guns is now 6 by default, down from 8, and now respects a new limit. It no longer spawns more guns if the map already has as many guns as (number of non-spectator players * ttt_floor_weapons_spawner_guns)

The new convar ttt_floor_weapons_spawner_near ignores this limit, but respects the entity limit (ttt_floor_weapons_spawner_limit)

Fixed lua error when other mods override a base TTT function this mod uses

Major update.

Now spawns weapons on the ground of maps that don't have enough or any, which should make any Gmod map playable with TTT! See the description for details.

Localised ammo-giving function

No longer triggers during the 'Murder' randomat, if the randomat and that event is installed

Made main convar non-archived to help not accidentally turning off the mod

Changed filename

Initial addon creation.
