Fix classes with missing/incorrect descriptions

[cjbrooks12]

There are a handful of classes that do not properly document themselves, or document themselves incorrectly. Orchid needs to be updated so that all common extension classes contain an @Description annotation on the class and all of its @Option properties, and that all of those descriptions are correct.

I think another related issue is availability / comprehensive documentation for those that would like to use and extend orchid. I found very little help or documentation while working on a plugin for work.
