[IMP] web: update jquery-ui to 1.11.2 version

reintroduce jquery-ui.css (smoothness theme) in the webclient as i earlier
deleted jquery.ui.bootstrap and I can't update it as it doesn't support
this verion of jquery-ui. This result in some style changes especially in the
form view notebook.
[FIX] view_form: notebook: jquery-ui v1.11.2 removed `select` method
