Feature additions

Hi,

Made some view changes to main listview to show more information for question. Also added
 - Sort page to select sorting type and order for questions
 - Search page containing free text search + tag based search, both can be used same time
 - Pushup menu for browsing questions 

Still planning:
 - User page, for browsing user infos by different sorting criterias
 - Own question, (+followed questions if possible) if userid somehow got saved after login
 - Filters (unanswered(default), all) for questions
 - List menu action e.g. to list all questions of that user or search with tags of that question (=similar questions)
