Wannier-file split up: ComputeMWLF() into smaller functions

This split up was done in the SVN repository and tested there and is working. It was impossible to piece it up into smaller chunks in order to maintain "bisectability", hence the last wannier.* from the SVN rep. was used. However, there was one bug in ParseWannierFile: There is the define "type" and there was a enum variable also of name type which caused errors on reading perturbed densities in the resulting shielding values. Removing the variable completely fixed this.
Note: With regards to the shielding values of c2h4 at 24Ht the resulting values are still absolutely the same as with revision initial_commit
