#11 Add optional hideFocus on links

[Morten Wang]

Some site-owners prefer having the dotted line around
links removed after the link is clicked. This has
previously been solved using onfocus="this.blur()",
and IE5.5+ also supports the attribute "hidefocus"
with value "true".

Add it as an option, and credit John Gregory for
helping out.

The dotted line will absolutely exist now that the menu
eases keyboard navigation through focus() usage. Make that
an optional setting, so that the calls aren't used. Just
make sure to let site owners know the consequence.
