Include static files into the main project.

Move the static files from http://static.tstettner.de/ to the root of
Project Icy.

Change every dependency to reflect the move.
Add new article placeholder for information.

Use the new article.warning placeholder $infoContent to return
information popups, joining $successContent and $errorContent.
Add a row update counter to News

When news feeds are updated $updateRowCount returns the affected rows
of this database query and pushes it to the information placeholder.
Merge functions to show articles from News feeds

Unify the article display functions and join the display behaviours.
Fix form submission

Some submit information were not set properly.
Fix 'Scroll to mark as read'

Finally fix the function to mark articles as read by scrolling through
them. Also works in all articles views.

This feature allows the reduction of initial loaded articles. From now
on Icy will not load more than 10 articles. In order to get more than
10 articles users have to (1) scroll to the bottom of the page or (2)
click the corresponding button.
