VampyrBytes de45fc9aba Cleans up slipping code 
Puts slipping into one proc rather than being dealt with individually by
each item.

The only changes to functionality here are where it would have been
possible to slip on some items whilst flying. It will make any changes
decided on in #3490 or any future changes far more easy to implement

/* 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.
