Started working on implementing parameter support into modifiers

So far the generated C code is already able to construct parameters
and pass them to the modifiers. However, this does not yet work with
chained modifiers. Also it isn't yet implemented in jit so that kind
of entirely breaks as well. Hence the new git branch.
Rewrote the C code generation of the modifiers

Modifiers are no longer chained within C
Parameters in modifiers seem to so far work through libjit

Although still not entirely done, no parameters are actually appended just yet
for example.
Implemented appending expressions to parameters from jit
