New features: better clustering, hovering topic descriptions, keyboard shortcuts

[Jonathan Stray]

Now live:

- Better clustering, again. The algorithm now uses a variable k-means approach... meaning that it splits each topic (node) into a variable number of pieces, between 2-5, depending on the structure of the documents. This results in much more interpretable topics.

- More keyboard shortcuts: select a node, then use the arrow keys to navigate through the tree, which will scroll to follow you

- Hovering topic descriptions: point to a topic with the mouse, and you'll see the description and number of documents hover over it.

- ISO 8859 character encoding fix. Previously some CSV files in this encoding would not import properly.
