Set Lwjgl3 to compile on Travis-ci.org

[huhlig]

Any reason why no nightly builds are setup? Travis-ci.org is free for open source projects.

The CI platform is hard to build LWJGL3 on (at least, I had enough problems that I just have it compile against my precompiled version)

I just submitted a patch for this. Have fun.

Thanks, I'll try to setup nightly builds soon.

Initial testing on Travis CI looks promising, at least for Linux and OS X. Need to figure out a solution for Windows builds (any recommendations?) and for artifact deployment (also for the GLFW and libFFI dependencies).

[Spasi]

Windows builds and artifact deployment have been resolved, nightly builds will soon be available.

Nightly build are now available. Details here.
