[tests] fix inline-creation/edition unit tests

cleanup, reorganize

[css] backported download box styles from forge

[forms] do similar refactoring for inline edition than for inline creation

merge

refactor to ease overriding

[inline forms] propagate kwargs to render_form

[forms] propagate parameters added to autoform method

[schema sync] fix so that new cardinality are considered when both inlined and cardinality change in the same transaction

a case for tidy : for your consideration

[uicfg] automatically set generated for the opposite of inlined relation as well

since we have the transition entity, give it directly

merge

this is actually a role, fix argument name

fix vocab param to avoid deprecation warning

fix case insensitive selector for entity creation

[selector] check read perm if action is add/update/delete

don't want this

[validatecontroller] allow additional args to be passed to the js callback

[javascript] make inlinedform-added event bindable $(form).trigger('inlinedform-added') was not usable since form had no existence outside the inner callback. Use the general CubicWeb object to trigger the event so it's easy to bind a callback wherever it's needed.

[forms] take a look at inlined form to guess whether the form requires multipart or not

[form] simply skip unknown argument given to form constructor, don't fail

fix argument given to changestate form selection

can't use anymore make_uid to generate a valid js var name
