OPENPGP PLUGIN: Don't list expired/revoked GPG keyopenpgp-plugin-hide-revoked-expired

	- closes #91
	- Mention that GPG key may be expired or revoked in chat input
	box
	- in the account dialog if the number of OpenPGP keys found is
	0, the label also notes that a key may have been revoked or
	expired.
	- blocks input in chat box if key is use is revoked or expired
	  when switching conversation and can detect if your key has expired
	  while chatting
	- if current selected key is revoked or expired, it'll be shown
	  in account manager with a warning message: "Attention
	  required: your key xxxx is revoked/expired!"
