unify naming of GPG/OpenPGP
problem
Gajim does not refer to OpenPGP encryption in a consistent way. Sometimes it's called "OpenPGP", other times it's called "GPG".
The chat window, e.g., displays
[timestamp] GPG encryption enabled
while the menu to toggle encryption displays
Toggle OpenPGP Encryption
analysis
This is just a minor problem, many may consider it a purely cosmetic nuisance. However, as people may refer to this particular feature with several names, it leads to increased costs when investigating issues with GPG/OpenPGP encryption in Gajim, i.e. people need to search for "GPG" as well as "OpenPGP".
enhancement recommendation
Please unify the naming of GPG/OpenPGP encryption. As "OpenPGP" is the standard itself and "GPG" merely an implementation thereof (https://tools.ietf.org/html/rfc4880), I suggest using "OpenPGP" as the name to be used.
