Refactoring (Map): initial phase

[Konstiman]

This PR introduces the 1st part of the knowledge map component refactoring. I refactored everything at once (chart + bubbles + papers).

The new code can be tested by building the application with MODERN_FRONTEND=true.

Main features:

Libraries:

• I installed one new library: react-hyphen. I use it for hyphenating the paper content.
• d3 sub-libraries were added (somehow d3 didn't work without them in the new code)

Redux:

• New actions and reducers for handling force layout and animations added.
• If the animation is running, all actions (with some exceptions) are queued and triggered after the animation finishes.
• New middlewares that do things unrelated to the legacy code - scrolling, queuing, force layout, streamgraph detection.
• Most reducers were changed to support the queuing.

Components:

• Highlight component had to change so it supports hyphenated strings.
• New components KnowledgeMap, Chart, Bubble and Paper.
• BubbleTitle component encapsulates the old highlighting + hyphenating + truncating logic.

Legacy code:

• Disabled a lot of code in canvas.js, bubbles.js, papers.js and list.js.
• Refactored the dimension computation into a separate file.

Testing:

• No unit tests yet.

Known bugs:

• Wrong map height in LinkedCat (both knowledge map and streamgraph).
