Move non-Wikipedia-specific graph code from graphconnectivity.wikipedia to graphconnectivity

When fixing Issue 34 it turned out all the code in the 
graphconnectivity.iterative.* packages depends on JWPL and/or DKPro 
Similarity's Wikipedia API.  From reading the comments I assume this wasn't 
meant to be so; the graphconnectivity.iterative and 
graphconnectivity.iterative.util packages were supposed to be generic classes 
for iterative graph connectivity algorithms, and the Wikipedia-specific 
versions of these are supposed to be in graphconnectivity.iterative.wikipedia 
and graphconnectivity.iterative.wikipedia.util.  But code in the former two 
packages is actually dependent on classes from the latter two packages.  So for 
now all of them have been split off into a separate module, 
de.tudarmstadt.ukp.dkpro.wsd.graphconnectivity.wikipedia.

In the future it would be great if we could remove the Wikipedia dependencies 
from the graphconnectivity.iterative and graphconnectivity.iterative.util 
packages and move the classes back to the 
de.tudarmstadt.ukp.dkpro.wsd.graphconnectivity module.
