Refs #1996

I open a cache in a country of which I cannot understand the language. I select the description text and send it to the Microsoft translator app and try to understand it there. No picture is shown.

Describe the solution you'd like
I would love to have a button to toggle the language of the description. c:geo should send the text to a translation service and report back the translated text. Keep the pictures at the same.position.

Describe alternatives you've considered
Open web page in Chrome, translate there. Use Microsoft translation all.

we used to have at leat a context link to Google Translator which should still be there if you mark some text in description or log.

Anyhow it would of course be interesting to offer some inline translation.

Is there a translation service providing an API which is free to use?
