Andreas Otto 87155d1cc2 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 Homebrew/homebrew#4201.

Please read http://www.gnupg.org/faq/why-not-idea.en.html before doing so.
You will then need to add the following line to your ~/.gnupg/gpg.conf or
~/.gnupg/options file:
load-extension idea
