Use relative translate on commands

[fersilva16]

Now we use t('commands:command_name.a.b.c'), and ends up we repeats too much commands:command_name.

Basically, the idea is: if the path not starts with namespace (commands: for example) this t starts getting translation from root, else auto adds commands:command_name on start.

Not really sure about how we would do that, as the t function is managed by i18next

Oh wait I think i18next has a thing for that

This might be of some help, but I'm not sure it would allow us to prefix the command name, but only the commands namespace.
