Commit before implementing client-side SSL authorization
- Commit after implementing client-side certificate autentication and
before removing checkboxes that manually allow to do that - we will
instead automatically try to recognize when server may require
client-side certificate
Made some improvements over automatically sensing when server requires
client certificate. Now I will proceed to delete check boxes which were
indicating manually that we will use client side certificate
Fully implemented client-ceertificate authorization using keychain.
Unfortunatelly since Android 4.1 there is a bug in a system and app
randomly crashed and shows in log only: Fatal signal 11 Code=1
Implemented client certificate authorization for IMAP.
Fixed every known bugs and added few dialogs like for showing lack of
support below ver. 4.0 and asking to install certificates if there are
none.
