Skin Updates

I updated all three skins: Gemini, FixFlow and Triad as well as Cookbook:ShowHide.

These updates fix a few bugs:

The latest Cookbook:ShowHide script can now be installed without causing a fatal error (it needed to be deinstalled before, because the skins include their own version, now they will not load it and use the installed version instead).
Fixflow and Gemini can now also use lnav and rnav divs, as Triad does, to give a topmenu with items both left and right. Use >>lnav<< and >>rnav<< to group the list items (same as Triad, so the PageTopMenu can work for all three without conditionals.
The cookie settings have been improved, as there was a confusion of cookie naming. Now the skins create cookies for optional color, font etc settings with a skin-specific name and won't confuse each other any longer. The fontsizer cookie is shared by all three. A cookie set by javascript to indicate for php that javascript is enabled is now improved and does not appear in multiple ways any longer.
