Nerfs Lava Staff (#13971)

* Nerfs Lava Staff so it cannot be used outside mining z level

Added  a timer and a spark system to spawn sparks when lava staff malfuntions.

Lava staff will check what z level is his user on, and if it's not mining will only spawn a few sparks.

* Updates description

Old description made little sense as lava staff will no longer work at the emergency shuttle.

* Update code/modules/mining/lavaland/loot/ashdragon_loot.dm

Adds spaces between method call parameters.

* Removes unused spark effect system

Since I'm using do_spark() I don t really need a whole spark system.

* Gets rid of "timerMalfuntion" var

Instead of using 2 variables to do the same, "timer" will now control the cooldown for when the staff works and for when it malfunctions.

* Removes unnecesary time check

* Update code/modules/mining/lavaland/loot/ashdragon_loot.dm as suggested by @farie82
