Fixes #3986 - Foam reagent inheritance fixed: The trans_to() proc in Chemistry-Holder.dm was calling handle_reactions() every time it would add and remove reagents with add_reagent() and remove_reagent(). I've added a safety flag to both of these procs (and copy_to()) so that trans_to will not call handle_reactions() until it has added all the reagents to the target container. This allows foam to reliably take on the properties of other leftover reagents. - Fixed a bug in effect_system.dm that wasn't applying reagents from foam to the environment. - Tweaked smoke to apply reagent effects after it has stopped moving This was causing huge reagent spam at the center of the smoke cloud as it was spawning, since they were being applied every time the cloud of smoke moved. Also changed it to apply the effects 2-3 times at longer intervals (2 seconds). - Smoke also only effects tiles in a 3x3 grid now, rather than 5x5. - Summary: Chem smoke does slightly less damage (if it contains damaging reagents) Chem smoke proc calls reduced by 60-70% (significant lag reduction) Foam works properly again Foam proc calls reduced by 70-80%

/* This is an attempt to make some easily reusable "particle" type effect, to stop the code
|
|
constantly having to be rewritten. An item like the jetpack that uses the ion_trail_follow system, just has one
|
|
defined, then set up when it is created with New(). Then this same system can just be reused each time
|
|
it needs to create more trails.A beaker could have a steam_trail_follow system set up, then the steam
|
|
would spawn and follow the beaker, even if it is carried or thrown.
