quick_frontend(contact list): refactored update:
update is now called with appropriate constant value (C.UPDATE_ADD, C.UPDATE_DELETE, C.UPDATE_MODIFY and so on) when a widget change visibility according to current options.
Before it was linked to cache only (C.UPDATE_ADD was only called when contact was first added to cache).
This make widget handling in frontends more easy.
Renamed entityToShow to entityVisible, which seems to correspond better.
Started reducing lines lenght to 90 chars as a test. May become the new coding style soon.
