Create binaries with libsnark disabled on new tags (#319)

* add appveyor, travis, remove libsnark as default, add push to gh

* fix appveyor

* change appveyor to nightly

* use cargo for build job

* change to build everywhere

* update token, reduce targets

* add more targets

* add on liner script

* remove rustc dep

* add need_cmd

* add check cmd

* simple brackets

* use check_cmd for curl

* copy stdlib to OUT_DIR

* ship stdlib in archive

* install stdlib, give PATH hints after build script

* clean

* comment

* scripts: ensure one-liner install script works with FreeBSD

* remove appveyor for now

* clean, remove windows, remove appveyor, remove travis test

* put back cross install

* fix stdlib test generation

* disable tests in travis

* restore test script to prevent tests to run..

* change scripts to keep same behaviour now that libsnark is disabled by default

* update docs with installer

* change docker to dockerhub

* change repo

.travis.yml
