Stable release

This is basically the 0.1.0 release with some extra debugging support (see Settings/System tab) and a number of security patches applied. Since this has been in continuous use for over 2 years by a number of people and without major issues, I've decided to make it version 1.0.0.

First release!

Basic stuff is working. This includes:

• identifying and blocking/unblocking callers;
• Phonebook search;
• adding/editing contacts.
