Adding English Content

In 'lang' dir you can now add new language-specific items. It should first be added for English and then, eventually, ported into other 
languages. Procedure is follows:
Adding new content:

   1. Add new content to the relevant file under English (en) directory and, after each line, add a comment like: // to translate.
   2. Add this English content symmetrically to every relevant file in other language folders. (Keep 'to translate' comments)
   3. Create a detailed task (tracker?) item assigned to whoever is responsible for translations. 

Modifying existing data

   1. Do changes first under English (en)
   2. Add this English content symmetrically to every relevant file in other language folders right under the same, already translated, line.
   3. Comment the line(s) with '//'
   4. Create a detailed task (tracker?) item assigned to whoever is responsible for translations.
