Add Options control to ribbon and prep. Sigstat
* src/gpgoladdin.cpp (getCustomUI): Add dialogBoxLauncher for opts. (getCustomUI): Prepare for status in reader window. (GpgolRibbonExtender::Invoke): Call the functions. (GpgolRibbonExtender::GetIDsOfNames): New names. * src/mail.cpp (Mail::insert_plaintext): Invalidate ribbon. * src/ribbon-callbacks.cpp (get_crypt_status): New. * src/ribbon-callbacks.h: Add prototypes
The signature status code basically works but the UI does not
work. Using toggle buttons does not work because the user can
change them. Disabling them greys them out and this does not
look right.
