Merge branch 'master' of git://github.com/JuliaOpt/JuMP.jl
prep for 0.6.3
fix printing test, ref #288
enable travis testing on os x

rearrange travis builds

switch to @tkelman's travis script
Merge pull request #289 from JuliaOpt/travis_osx

enable travis testing on os x
remove unneeded workaround
reorganize NLP code for speed
Add unbounded test (only Ipopt passes)
nonlinear objectives were displayed as feasibility problems
make ArrayViews dependency required
forgot to import ArrayViews
add test for fd6ded5
Create a test/REQUIRE file, so PkgEval will also test nonlinear

Currently PkgEval has a hack in it to install Cbc/Clp/GLPK, but this is a better way to do it and to also do Ipopt.
This requires us to go back to old-style running of tests in `.travis.yml`
Update Travis to account for the fact we don't want to use test/REQUIRE on Travis
document KNITRO interface
fix show for empty models
allow sets of quadratic constraints via @addConstraint
remove cruft
add three-argument version of @addNLConstraint, closes #214
