Fix a bug in the review widget and speed up jumping to low node-count
fragments

The issue arose when calling initReviewSegment with an index
that was based off an array extracted with .slice() which does
not match the skeleton_segments index.
Add review puffer when reaching end of segment to review
Slice caching in pure javascript
Remove unused cache_image Python code
Remove caching from urls.py
Upper limit on the number of nodes to cache
Lower node counter for tile caching
Use a tile counter and fix bug in the caching regarding segment status checks
Graph: remove console.log statement
Circuit Graph Plot: created new dimension "Graph partition (cell types)"
which combines:

* for disjoint networks, the second and third eigenvectors
by getting the non-zero values.

* for single-component networks, combines the third and fourth eigenvectors
according to the sign in the second eigenvector. The positive values
in the second eigenvector are then picked from the third or the fourth,
depending upon which has the highest standard deviation for these values.

The effect is that neurons that are connected to similar sets of neurons
in similar ways will end up together in this dimension, which effectively
identifies cell types by connectivity patterns.
Merge branch 'master' of github.com:acardona/CATMAID
Circuit Graph Plot: add a mirrored version of the "Graph partition" dimension.

Additionally, fix numerical instability errors: near-zero values are now zero.
Circuit Graph Plot: fix potential error in choosing positive values
when there are numerical instabilities.

Add option to speed-up remote review with checkbox.

Default is false, which is the old behavior using E to go to the next
segment. If enabled (true), after 2 times pressing W it automatically
jumps to the next unreviewed segment, sets the actual segment's review
status to 100.00 on the client side and does not refresh the widget,
thus speeding up reviewing of the long tail of very short segments.
