Use the same functions as for the list-style property since only the "type" part
of the list-style property is supported at this stage.

Recognise the list-style property and apply it by setting the
appropriate flag on the element's parattr based on the property's value.
Add test/list-style.html with an example of each possible list-style
value (many are unsupported by the HTML engine).
After commit b66d2bec67 'document: Unify text style -> screen attribute handling', the case statements for CSS_PT_FONT_WEIGHT, CSS_PT_FONT_STYLE, and CSS_PT_TEXT_DECORATION all have common code and therefore collapse nicely.
...as struct text_style. This way it might be possible later to
add other default formatting attributes by CSS and it allows
quite a code simplification in the DOM renderer.
Currently, all DOM, HTML and plain renderers had their own routine for
conversion from text style to screen attribute. This moves text_style and
text_style_format from html/parser.h to renderer.h and introduces new generic
routine get_screen_chracter_template() that is used by all the specific
rendering engines.
Now, CSS is initialized separately for each of the renderers, so that
also RSS doesn't just choose styles of random DOM node types.
init_template_by_style() is introduced as the common backend for
loading CSS properties.
