Make GPG optional

[diegobfernandez]

I can't use the plugin because I don't have GPG installed. I have no plans on encrypting the connection files as I am only connecting to local databases that are already pretty accessible.

This is the output I get when running :PGConnectBuffer

Doesn't even work with gpg-sute installed on mac

Seems like it's trying to get gpg from /usr/bin while it's on /usr/local/bin
