Travis: enforce shellscript coding style

* enormous coding style update

* update luajit-launcher

All changes are formatting only except for:

* new more correct pushd/popd style
	* keeps useful indentation
	* prevents execution of commands when pushd failed (cf. https://github.com/koalaman/shellcheck/wiki/SC2164 and https://github.com/koalaman/shellcheck/issues/863)

```
pushd some_dir && {
    command1
    command2
} || exit
popd
