Add context to short action names

While I translated a lot of strings in past week I came more an more to the belief that we should add a context to action links.

Just one example I found have been:

Download

• Could be an action like "Click here to download"
• Or just mean "This is a download".

I've found some more of these, but missed to document them. I suggest to add a translatable string context name like Action.
