BLD: New build matrix for Travis
- Moved travis build logic to ci directory.
- Added testing for 3.3  (with numpy 1.7b2).
- Prints version strings for all installed components.
- added FULL_DEPS build for 2.7 and 3.2, which includes
  scipy and matplotlib tests.
- Made the log less verbose.
- Travis now shows an "env" columnn.

wes, "announcing" "official" 3.3 support in 0.10 might be nice, now that the CI is in place.
 I shall do that
 still needs fixing.
 should be good now.
 We can probably drop 3.1 soon (does anyone use it, really?)
