forgot 3rd party libs dirname match in regexp

moved 3rd party libs separately ; added a script to adapt relative paths in the html for production ; started harmonizing documentation

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

cf. ProjectExplorer commit eb8da4a4

NB: when the directory and code structure will be stabilized in tina2, this could be done by git-tree and pulling upstream from changes like https://github.com/moma/ProjectExplorer/commit/cb15c69

+ 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)

NB could benefit from SystemState().selectionRels

we need both neighbor agregated sums AND detailed info
