Changed viewport settings on index.html, added coverage data
Added VerticalCenter Directive

Switched in SameHeight Directive as well as VerticalCenter Directive to 
preLink Compilation. This could cause issues in the future,
since it is possible, that the SameHeightDirective calculates 
a wrong height, since the child elements have not been linked yet.

This will cause troubles, if child elements have directives that
manipulate the DOM.
Refactored RouteResolver so it would allow for the loading of entire
component sets.
Added HoverIntend Directive
Added Youtube Directive
Moved Header less files to the header components directory
Minor changes
Added Header Set, which defines dependencies of the 
header component

Unfortunately, the header component cannot be lazy loaded via
the RouteResolver, because the header is directly included in the
index.html and therefore compiled before the StateManager kicks in.
