Currently, the "kanban compiler" parses the XML and post-processes all
dropdowns defined in the view.
This commit adds a "kanban_ignore_dropdown" class, allowing to ignore this
additional post-processing if one wants to add simple dropdowns within his
kanban cards that are not transformed by the compiler.
This will be useful notably for the social_twitter kanban where we use a
regular dropdown to show re-tweet options.
