Run tests on travis-ci

[kadel]

related to #34

• run commandline tests and unit test on travis-ci (make test-unit and make test-cmd)
• make binary builds only binary for current arch platform where script is running (no cross compiling)
• added make binary-cross same as former make binary (cross compile for mac/linux/win 386/amd65)

command line test is failing because of #88 and #92

+1, we just need to check the tests

👍 @kadel. I will check this after dinner.

@kadel I tested on ubuntu 16.04.

• make binary-cross doesn't output binaries.
• make binary-cross and make binary doesn't print anything. It would be better to print output then user can see what's happening like this:

$ make binary
./script/make.sh binary
---> Making bundle: binary (in .)

Number of parallel builds: 1

ahh my bad 😄 make binary-cross points to makes.sh binary, to it just builds for current platform :-) I'll fix that and I'll also add info about successful build for make binary.

Thank you for noticing that.
