[development] Overriding CSS files in themes

[Steve Ringwood]

	Actually while what you say about calling

	theme('add_style', drupal_get_path('module', 'mymodule').'/mymodule.css');

	instead of

	theme_add_style(drupal_get_path('module', 'mymodule')).'/mymodule.css');

	makes sense, it has the un-intended side effect of initializing the theme
subsystem
	and making it hard/impossible to override the theme being used.  This
	is in part due to the css/js being included in the menu hook which is also
	often used as a place to overrride themes.

	I would argue the answer is not to use a theme function (i.e.
theme_add_style)
	since the direct call means it can not be override any how.  It seems that
	a more general solution should be provided that takes the files to add
(mymodule.css)
	and a prefereed path ( drupal_get_path('module', 'mymodule')) which is used
if the file
	(mymodule.css) does not exist in the "current" themes directory.
