  Travis: simplify the lump of programs installed all at once, for speed.
  Travis: Check php ini settings before trying to install composer.
  Travis: Don't fail on all errors, arg.
  Travis: Allow failure on php 5.3.3 because openssl is unavailable.....  so composer fails to be able to download stuff.
  Travis: Update travis to just do an apt-check for openssl, and list app versions after failure.
  Travis: Don't bother building for 5.3.3 since it will fail, build for 5.3.6 instead.
