Added new functions to PageManager:
- findAllRouteModules([$name = null])
- findRouteModule($name);

This add the ability for actions to modify the routemodule objects e.g.
for adding additional assets.
Fixed image counter. ExportImages should now show the correct amount of
images exported from modules.
Fixed a problem in the AsseticHelper.

This fix allows the AssetHelper functions findImages and findFonts to
find css constellations without quotes or doublequotes.
Fixed a Pathresolving problem.

During this problem the ExportView Action was unable to build local
paths for some assets. This problem occured after adding a assetfile
which were not within the web path.
