Fix type conversion on calling LSL functions.

We had a big chaos with type conversion. That caused a bug where passing a key to a function that required a string, or vice versa, crashed the script.

Diminish the chaos by modifying the parameters just prior to invocation (in lslfoldconst). We also remove the, now unnecessary, calls to force floats, either alone or within vectors or quaternions.
