polyvalent but esp. used for https://github.com/moma/comex2/commit/1b5c4b7

POSSIBLE: remove settings_explorerjs.js from the repo and ask the users to create it from twpresets/settings_explorerjs.devdefault.js ?

this allows to fix problems where db details from conf were not unique and only the last one was used

kanban #271

for any scholar s, for all scholar's terms t_i, Σ(wei(s,t_i)) = constant

fixed again easytabs init (inner and outer div both necessary resp for readmore and tabs) and unify tab css with the reldocs tabs

added an optional reserved attribute 'normfactor' for this...

read db.json conf for all sourcemodes, better reset graph at init, pass db.json node names conf to parsing for sortNodeTypes

read the db.json extended format in php + rationalize passed url params

reldocs redeclared for each new sigma instance + reldocs are now sorted in separate tabs by nodetype + the nodetypes/dbtypes combinations are handled in db.json conf + tabs logic (instead of being handled by ajax logic) + removed legacy types from php queries (changes in php under way)
