Subject: Add option for 8192 bit GPG keys.

Although it is technicaly possible to work with 8192 bit GPG keys the
creators of Gnupgp ship the sources with a hard coded limit of 4096
bit. If you want a larger GPG key than 4096 bit you're supposed to
change the given limit yourself by changing one line of code in the file
g10/keygen.c. That's it. After that you can create 8192 bit GPG keys.

Closes #4201.
