Enable actions that are specific to double extensions like .pgm.clle or .pgm.rpgle

We use the naming convention where a .rpgle or .clle extension is for modules, whereas .pgm.rpgle or .pgm.clle is for bound programs.
Right now, there is no way to have actions specific to modules vs. bound programs.

It would be nice to have the ability to define actions specific to the .pgm.rpgle/.pgm.clle source types (CRTBNDCL/CRTBNDRPG) and the .rpgle/.clle types (CRTCLMOD, CRTRPGMOD).
