[FIX] ir_qweb groups: in order to compute the groups of a user, we are using cr and uid from request. In case we are rendering the template in a non-request context (for instance, automated tests), we have no cr and uid ; do not compute the user groups in this case.
[FIX] Adapted the render_report and try_report_action methods used in yml test to work with qweb reports
[FIX] as render_report is adapted to qweb, no need to filter in _exec_action

[IMP] ir_qweb: added t-esc-options to allow customization of a t-esc; added an ir.qweb.widget model to format the t-esc value depending on the 'widget' key of t-esc-options; added ir.qweb.widget.monetary
