timer code improvements

logic improvements and mod structure changes

added two new functions to override by server owners for special needs:

SWAZBF.specialCheck(zombie, wielder, weapon, userName) override with server special checks, for instance disable mod in event zones, this function have to return either true or false, inspect the file for an example

SWAZBF.specialFunction(zombie, wielder, userName, killboxType) override with server special code to be executed together with Destruction code or instead of it if so desired, inspect the file for an example

small bug fix
code optimization
sandbox settings changes, if you did change something from defaults before this update, consider checking those

added extra arguments to SWAZBF.findAndDestroy(zombie, wielder, userName, killboxType) function in case some servers would like to override it with extra custom code like log extension or maybe set the cheeser on fire kek

hotfix, sorry

based on the feedback there's now different minimum required amount of hits depending on Weapon Multi Hit setting:
Without Multi Hit: 4 hits to warn, 8 hits to destroy
With Multi Hit: 6 to warn, 11 to destroy

Timer now resets in 30 irl seconds after being triggered instead of every 10 ingame minutes

code clean up
