fixes overview menu item by making overview the default
use wiki styles in textilizable block
use h3 as standard heading, just like all other blocks do.

use wiki styles across all blocks
loading the jstoolbar files only once

go into edit mode automatically when a new box was added
[designfix] replace inline styles with css, fixes design
[designfix] news should look like all the other widgets
[designfix] the ".overview" css should only match on divs

rename wiki block to projectdescription as that is what it has been anyway
[breadcrumb] overwrite default breadcrumb text
