Minor adjustment to add a bit of flexibility to tabs.
Minor adjustment to add a bit of flexibility to tabs.

/cs_tabs.class.php:
	* display_tabs():
		-- add "cleanTitle" to the (small) list of things that can be parsed
		into the tab template: it is basically the title, but stripped-down to
		alphanumerics ONLY, with anything else replaced with underscores. 
		-- NOTE::: in a title that has multiple replaced characters in a row,
		they will have the corresponding number of underscores.  For instance,
		"My - Tab" would become "My___Tab".
