Split plugin classes and derive AIFilePicker from BasicPluginBase (part 3).
This commit deletes all indra/media_plugins and copied one-on-one the indra/plugins directory from my (imprudence) statemachine branch (which contains the AIFilePicker patch). git shows this as a lot of 'renamed' files because originally it was a rename. However, there are a lot of changes as well: it's both an upgrade to a newer plugin system (changes by LL) as well as an upgrade to my refactored plugin system with a file picker as plugin. Since this commit is a one-on-one copy, it disregards any changes that were in Singularity and not in imprudence in indra/media_plugins however. I will add those back in the next commit.
