Plugin changes for #10
Plugins now get passed a parsed json object if a json file exists in $input/_data folder, if not an empty object is passed.
More plugin progress for #10
Make sure `config.data` and `config.data.plugins` access works.
Keep the original plugin name case as the name should match its config file in $input/_data.
Set the parsed json file and add to config eg `config.data.plugins.$name.$json`
