Diff to previous 3567
- Added an option to be have "THEORIES=all" in mk/config
(instead of THEORIES="long list of theories").
I will change all my nightly scripts to use THEORIES=all.

- Added mc to the default list of TEXTHEORIES. Added a file all-bodies.tex
that would automatically contain \inputs corresponding to TEXTHEORIES.
(Before this change we had to update all-theories.tex by hands whenever TEXTHEORIES
was changed).

- Minor fixes in some display forms.

- Removed theories/caml that never had anything useful.

- Removed a few files from theories/ocaml_doc that seemed to be there by accident
(Jason, can you confirm?).

1. Redefined inverse image. Previously it was defined by introduction
   and elimination rules; now it can be rewritten with "setbvd_prop".
   Actually, after "setbvd_prop" is defined, the "inv_image" is somewhat
   unnecessary. I keep it here just in case that people may want to use
   the concept of inverse image sometimes.
2. Fixed the error in the previous member elimination rule.

Added the module for the inverse image of set t in set s under function f:
   { x in s | f(x) in t }

I didn't find a direct way to define it, so I define it using axioms.
