announcing the deployment policy ('everything goes to static') before making directory structure changes and tidying up the project

+ new flag TW.gui.smallView for monitoring if current width < 768

simply change TW.conf.sidePanelSize to adjust the side panel setting, without affecting small viewport variants (with panel at full width)

with this optional cache, indexation happens only once every 1800s, and subsequent queries retrieve the search base (aka postings) from a serialized version in cache

(mistakenly removed in 2cf9e030)

(This reverts commit 4dabe1ef.)

(and other rounding issue with samerange)

display empty bins if samerange, show unrounded values on range thresh hover, normalize empty bin treatment, write exemplar colors directly in TW.Clusters etc

(forgotten part from last commit 2232005f)

2 x refresh was not necessary because invoked by executeNodeMouseMove
