create `mm fileout` command for doing a fileout of a full configuration .... `gs fileout` command finished up for this round:

  - one file per class (will change this to allow for alternate groupings)
  - extension methods overrideds changed in place in existing files new
    methods added to end
  - hard-wired class to filename map (will make this an option)
pull filename map out as arg to `mc filout` API which filters over to changes in the `fs fileout` API.
add variant of `mc fileout`/`gs fileout` API that writes class defs to one file and class methods to another file ... this is the one I will use for deploying Indexing changes for GemStone 3.2.
