Switch Language Icon

[josefkreitmayer]

We noticed, that an icon would be very helpful to be in the menu interface instead of the "change language" written description. The very good example of wikibase was leading us to the idea to search for an adequat option for the transformap-viewer.

Wikibase example, left of the language selector on the top right: https://base.transformap.co

I found several options we could build on:

1. http://www.languageicon.org/ is an initiative with the aim to provide an international language icon. They operate a "relax" license, which states "You are suggested but not required to attribute the work when using for internet / digital use.".
   Here it can be seen in different sizes: http://fontawesome.io/icon/language/

2. https://commons.wikimedia.org/wiki/File:VisualEditor_-_Icon_-_Language.svg is the letters used in the wikibase example. I do not understand the license to be honest.

3. another not as beautiful possibility with attribution / share alike license: https://commons.wikimedia.org/wiki/File:Icon_-_Foreign_characters_gray.svg

@species what do you think?
The first option would be my favorite, from the idea and license.
