split out parser modes into their own files

This moves all the parser classes into their own namespace and files.
Next up are the handler classes.

I'm not sure about the namespace, yet. A nested namepspace Parser\Modes
would probably make more sense... we'll see.

This also removes the duplicated coded in the Plugin mode. We now use
the plugin trait and can inherit from AbstractMode instead.
