Make -new-comp the default and bump the version number to 3.3.11-darcs

* -new-comp (the new partial evaluator) is now chosen by default when you run
  cabal install (or cabal configure). To revert to using the old partial
  evaluator by default, use "cabal install -f-new-comp" (or
  "cabal configure -f-new-comp").

* Regardless of the configured default, you can choose which partial evaluator
  to use when you invoke gf by using the -new-comp or -old-comp command line
  option.

* The cc command in the GF shell uses the chosen partial evaluator by default,
  but you can override this by using "cc -new" or "cc -old".

The plan is that these flags will be romeved in a future version.
