Remove jshint as the license is not ASL compatible

[Matthias Runge]

We bundle jshint in horizon, but don't include the license, despite it says:

The above copyright notice and this permission notice shall be
included in all copies or substantial portions of the Software.

turns out to be worse. jshint license uses this silly:

"The Software shall be used for Good, not Evil."

Which makes it incompatible.

[Matthias Runge (mrunge)]

we need to drop that asap.

License clarification requested upstream: https://github.com/jshint/jshint/issues/1481

[Matthias Runge (mrunge)]

Original author said, he won't change jshint license, so it must be considered as non-free.
