Learning to use Butterknife, refactoring small things.
CW loads, but no provider list appears.
Renderers and dagger, refactoring CW.
Click on an item, no UI but functional.
Switching provider doesn't refresh provider list.

It shows just one provider, and it's not the one that gets configured if
selected.
Release flavor updated, back button works.
Show all providers onCreate CW.
EIP fragment shown correctly.
Save custom providers to sdcard.
No duplicated providers.
Final refactoring for this bug.

Removed the sign up dialog, log in one is enough with the third button I
added some time ago to sign up.

Removed classes we don't need due to the libraries I have recently
introduced.
Bug in the add provider to the adapter fixed.

Refactored the new provider dialog too.
SessionDialog restores eip switch if necessary.
Restore eip service UI onResume.
