[ADD] web: Allow to add multiple records in m2m_tags widget.

Before this commit when user want to add multiple record at that time
they only allow to add one record at a time.

After this commit user can add multiple record from search more wizard.

Added function _getSearchCreatePopupOptions so that it can be overridden
in FieldMany2ManyTags, options for FieldMany2ManyTags will differ, like
FieldMany2ManyTags SearchCreateDailog should have multi record selection,
Many2ManyTags' SelectCreateDialog should display record other than selected
