Add signatures
This adds the ability for per-account signatures in the accounts.conf config file. The signature is added to emails in the editor at the bottom of the email. This includes when forwarding, replying to, and composing emails. There are two config options: signature-file and signature-cmd. The former allows a signature to be read from a file and the latter allows an arbitrary command to be executed to return the signature. The config options have been documented in aerc-config
