replace jsdoc with a non-abandoned project

[chadxz]

It seems that jsdoc has been abandoned... most people that want to see patches land in the project have decided to just fork it and make the changes themselves. I know that @ruffrey also has a fork of the project called jsdoxy.

In any case, we should move away from this package if we want to make sure we get updates to its dependencies and any bugs fixed ever.
