Add localization guide, minor changes

[gitlimes]

This should make it easier for first-time translators to localize the project.

• Added general localization guidelines
• Added localization instructions for the main website
• Other minor changes

This is awesome, and makes translation much more accessible. It'd be great to have a working localization community since we're only going to gain more things that need it - Juxt, the patchers, splatfest texts, etc. My only thought is that maybe we should be hosting the localization tester ourselves?

+1 from me, should be merged

Thanks! I agree, it would probably make sense for someone that's part of the staff to host it, and/or use the official domain for this. The code is here btw.

Also I completely missed your comment the first time around sorry lol
