Build system for 'native' py plugins

[rejhgadellaa]

An idea:
Possible to read folder 'nfcpyr/plugins' and import all files as py modules??

Each module should have 4 methods that return a booleab(?) on success/failure:

• init(self, readerdict=None, userdict=None)
• on_scan(self, reader_id, username)
• on_checkin(...)
• on_checkout(...)

Config files should go in.. Json/ or pluginjson/?

These plugins could handle stuff like osc messages, zocp, philips hue, mpd, etc

Dynamically import modules:

Whoop. Done.

Well, it needs more docs and maybe a good review of the code and especially the examplePlugin. But it works!
