Adds a new script command 'modInvoke' to invoke registered functions

from region modules. The LSL translator is extended to generate the
modInvoke format of commands for directly inlined function calls.

A region module can register a function Test() with the name "Test".
LSL code can call that function as "Test()". The compiler will translate
that invocation into modInvoke("Test", ...)
