Translation japanese
Added jquery dependency to all files to make sure that its available when I add the translation later on
Fixed navigation: Changed from "a>li" to "li>a" because its html compatible; Added "current-page" class; Fixed css so current-page is actually shown.
Added id to be able to link to it with #writeups
Added ids & classes to write better selectors for the translation
Added id's to all workshoppers for better selection when translating
Added spans to paragraphs that allow to replace only paths of the paragraphs using javascript
Moved the text for event-count out of the javascript method into the html so it becomes translatable.
Moved the text for event loading out of the javascript method into the html so it becomes translatable.
