gpa-0.10.0-bp156.3.7

- No longer recommend -lang: supplements are in use

- update to 0.10.0:
  + Added key manager context menu items to copy the key
    fingerprint and the secret key to the clipboard.
  + Added "Details" buttons to many error popups to show raw
    diagnostic output from gpg.
  + Changed the "Retrieve Key" dialog to first try the Web Key
    Directory if a mail address is given.  Only if this lookup
    fails the keyservers are searched.
  + Added a user-ID notebook page to show per user-ID info.
  + Fixed crash on filename conversion error
  + Removed lazy loading of the secret keyring
- add upstream patch gpa-0.10.0-reduce-gpgme-requirement.patch
  to avoid requiring gpgme >= 0.11.x
