Added ignore and initial select options

[PocketNinjaDesign]

On using the plugin I realised I needed to do a few more settings based on the content we had on our site. Our dropdown menus were mostly clean classless li's with a couple that were styled different and had nothing to do with the menu but were just done that way.

Also when selecting an inital option outside of jquery-menu-aim, it seemed that the item would remain active until you hovered over it to then close it. Triggering the initial index seemed to be a quick option.

$menu.menuAim({
    activate: menuAimItemActive,
    deactivate: menuAimItemDeactivate,
    rowIgnoreSelector: '[data-tab-ignore]',
    initialActivate: 2
});
