Editor localization support

[Crimson Wizard]

Recently I was asked by Sledgy if I can help translate Editor to Russian language (from the technical side). This made me think that there might be other languages people would like to see the Editor translated to. But it currently has no direct localization support.

What are potential possibilities to add such support to the the application?
I had certain experience with localizing C# programs using resources tables, but it is hard for me to deduce whether AGS Editor is suitable for same technique.
Also, how viable it is, in theory, to have strings downloaded from the external file? (which could be edited by anyone without even having to commit to repository)
