[reledit] simplify, fixing #344545

consider primaryview_display_ctrl in reledit, XXX should split into reledit / autoreledit

new RelationTagsDict class, use it in uicfg where necessary

use msgid, update i18n

[skeleton] the new implementation of data_files will never raise a OSError

[formwidgets] let the textarea height be dependant on the actual content (up to a limit)

[reledit] allow composite edition if the composite is object

[js] small cleanup

[js] lint

oops

[reledit] do NOT propose to edit composite-related entities (unlinking would destroy the other side)

[formwidgets,formfields] hum, this way

merge

merge

[htmlhelpers] notes about seemingly unused functions (remove for cw 3.4 ?), cleanup a bit

[formfields,formwidgets] move default size and maxlength from field to widget init (that is quite still unsatisfactorily)

for some reason, use of an anonymous function makes things more readable

ability to map attributes to something else than usual cw mapping on sql generation

fix regression w/ NOT symetric relation (distinct not needed)

handle attribute selection on variable selected using MAX()

don't use internal address

added some assertion on expected hooks class attributes

rewrite test schema using a single schema file

[formwidgets] ensure textarea for richstring has not ridicuously small size (close #344547)

oops

[tests] make tests conform to new input/text size and manxlength

[reledit] there is nothing to escape, also cleanup lzone for attributes

[formfields] set a reasonable minimal minimum length to input/text, also set the max length if applicable (closes #344538)

[tests] needs repair

do nothing if the clicked facet has facetValueDisabled class; do not move facet when cubicweb:idx == 0

merge

optimize rql for ETypeFacet possible_values
