Was accidentally injecting the script object, not the string version of the code. Also
added a check so we only inject for Painless scripts (and not groovy, etc).
Minor style tweaks too.

This change adds licensing to the maching learning feature, and only allows access to machine learning if a trial or platinum license is installed.
Further, this change also renames `MlPlugin` to `MachineLearning` in line with the other feature plugin names and move the enabled setting to `XPackSettings`
