Do not use indexOf on arrays (breaks IE<9)

[ghost]

Considering that IE<9 doesn't have an .indexOf() function for Array, could you replace all its uses by $.inArray?

On "morebits.js" there are two functions using indexOf on arrays. The code result.indexOf( current ) === -1 from Array.prototype.uniq could be changed to $.inArray( current, result ) === -1

Analogously, the code uniques.indexOf( current ) === -1 from Array.prototype.dups could be changed to $.inArray( current, uniques ) === -1

Er... I just found another function using indexOf in the same js file. Somewhere in Wikipedia.page there is the code if (['recreate', 'createonly', 'nocreate'].indexOf(ctx.createOption) !== -1) { which could be changed to if ( $.inArray( ctx.createOption, ['recreate', 'createonly', 'nocreate'] ) !== -1) {

We do not plan to support IE <8. Upgrade to IE 9 if using Windows Vista or Windows 7, or use an alternative browser on earlier versions of Windows.
