macros (field, form, textbox): general improvments: - use a generic "field" macro for most fields - added "required" class on input labels if suitable - extra kw args are used as input field attributes. Same thing for forms - better handling of id if label is missing - added blog_text macro in textbox for basic text blog input - textbox is more customisable (class and textarea class can be specified)
