Add something about translation of attributes

[YetAnotherGerrit]

It is possible to translate attributes in trigger (and maybe text modules) with the following syntax:
#{t(ticket.state.name)}

This is not mentioned in the documentation yet and needs to be added.

@YetAnotherGerrit can you explain what you mean or give an example? For the general translatability, we have a note in the admin-docs.
But you probably mean another feature, right?

[YetAnotherGerrit]

When you phrase texts in text modules, trigger, scheduler, signatures you can use #{name} to include values of different attributes within. These can be translated using #{t(name)}. This is currently not mentioned in the documentation.

But is it really for all situations working? I'm not sure about the stuff which is replaced inside the frontend (e.g. text modules or signature).

[ralf401]

I tried it in text modules, trigger and scheduler. I wrote that it works in these 3 areas.

[ralf401]

Tested it again => just working in trigger and scheduler.

Pushed changes again to PR.
