Made modifiers_getVirtualModifierList safe for threading

Move static variables to context filling in by this fcuntion
and owned by a callee function. This ensures no conflicts
between threads happens because of static variables used in
this function.

Also moved modifier types and virtual modifiers data to a
function called from creator. This is needed to be sure all
the information is properly initialied to the time when
threads starts to use this data.
