feat(satteri): add option to silence warnings

[stephenlrandall]

Closes #170

Adds a warnings option to Satteri's compile options. Wasn't sure if a full logLevel-style option was warranted given that Satteri doesn't actually output much, so just stuck with a simple toggle to display or not display the warnings.

After discussion, swapped to a per-plugin warnings option.
