[IMP] web: various small improvements to form view

This commit is a few small improvement/fixes to the web framework:

- allow placeholder attribute on input tags in form view
- only bind click event handler to buttons managed by the framework, not
  custom ones
- _onExecuteAction method in action manager properly fails if event
  cannot be properly handled
