Signatures - signing subkey selection #156

You might want to consider that keys can have several subkeys eligible for signing so that a key selection could show subkeys, see image of how WinPT for GPG legacy handles this.

After some research on my part, the programming interface provided by GnuPG (GPGME) does not currently support specifying a specific subkey in an operation. However, GnuPG itself supports it with its command options. Things get a little more complicated, and I don't really want to go directly to GPG and operate through the interface they provide.

So, this requirement may be placed for a while longer. I may find time to provide them with feedback and expect them to provide such support.
