Htbulma

- just to make the package compatible with htag >= 0.7.0 (so htag 0.8.0 is compat ;-))
- adapt repo to ci/cd github


previous versions :

- new object: NavSide
- and fix some object to be able to autoset html_attribut / properties

- mbox.show don't use H anymore (so objects are attached to main page)
- add new object "Loader()" (spinner icon is-loading)
- "test.py", use DevApp now ;-)

* fix fileselect current path displayed was bugged

* fix the way the old param "onchange" is setted on new inputs

* all inputs use new htag features, and are more consistent .... and compatible with previous ones ! ....
(but DEPRECATED ... because in futures releases, it won't (remove .onchange() & .setValue() soon))

- readonly act like disabled (simpler)
- self.value : is a reactive property (setting it redraw the widget)
- all inputs send onchange event to set value on back side (reactive by default), in self.value
- every widget doesn't redraw itself on change (so doesn't blur the focus (except composite ones))
- _onchange is a classic onchange (chained with bind!) (htag.bind.prior can be removed !)
