Keep processes in proper lexical scope

Normally processes are found in the lexical scope of a module, but
there are special cases where processes (other then task/function
definitions) are in other lexical scopes. The most likely case is
initilizations that are in the lexical scope where the assigned
variable is declared.

In the process, the behaviors list is kept in the base PScope class
instead of the Module or any other derived lexical scope class.
