Noigeo pull request

A lot of changes to remove all the igeos from deegree desktop.
The project files are not adjusted, but the project compiles and a new project can be created.

So for installation that would upgrade to a noigeo version the following work needs to be done:
 * For existing modules not in the master branch one needs to 
  * adjust the imports to the new class and module names
  * adjust the configuration files to refer to the new names
 * Existing prj files need to be adjusted to refer the new class and module names

I am not 100% sure that is all, but that is what I did to get a version with working modules.
