Fix layout issue in skeleton analytics container.
Initial version of the synapse clustering python script.

Takes a skeleton ID or a graph representing it (and the synapses)
and returns data structures representing implicitly the groups of skeleton
nodes, each group being a synapse cluster.
graph.py can now split the skeletons further with synapse clustering.
The edges between circuit elements belonging to the same neuron are not yet implemented.

Added scipy=0.11.0 to pip-frozen, necessary for synapse clustering.
Reduced operations in graph.py and synapseclustering.py
from 0.33 to 0.29 seconds, and reduced memory footprint.
Most of the operations are in the dijkstra scipy side of things.
Slice widget
fixed resizing for 3d webglwindow
@Gerhard: Please change the camera according to the actual size of the
3d canvas to not stretch the display
Merge branch 'master' of github.com:acardona/CATMAID
added a slashtilesource for slash-separated tiles as those that we're
currently generating for Gerhard
Graph widget: synapse clustering results in minified arbors,
each node of the arbor connected to other nodes of other arbors
to make visible axo-axonic synapses, etc.
Removed a number of debugging statements.
Updated documentation
Added a new tile source type 5
