Renderer_ModelSearch: autocomplete now creates the base query using the model + better error handling on autocomplete + autocomplete uses jayps_search if available on the model + UI improvements
Renderer_ModelSearch: new renderer option to enable jayps_search on autocomplete search (disabled by default to prevent compatibility break)
Fix bug multiselect (quand valeur selectionnee n'est plus dans les options)
hotfix on hasmany.js (about 'this' changing in a function)
