The Census event is now replaced with module settings for populating the
protocols array. With this we can shutdown some plugins and still make
them be checked by TFN.
The performance:high config is now added when deciding whether or not to

default:
- Add default values for the TFN protocol setting
EVENTS:
- Remove Cencus event
TheFreeNetworkModule
- Remove Census event handler, update protocols array to use module's settings
- Use performance:high config when deciding to do online lookup

considering 'NULL' strings as SQL NULLs.
