Fixes #1006
add scale_option to snopt

really i should go through and add them all in one commit
re-enable most of -Wall, see #618
remove the WITH_BUILD_IPOPT feature

No-one is using it (even me), and I don't even know if it works. I think that using Ipopt from debian packages/homebrew is the way to go, see #1010

99% deleting trailing whitespace, also removed a few newlines
delete trailing whitespace in top-level CMakeLists
Changed Simulator output signature from times-by-states to states-by-time, #554

Merge branch 'develop' of github.com:casadi/casadi into develop
