Allow members to choose children skins while hiding the parent skin

[TomasMilian]

I bought 2 new skins for my forums (one dark, one light) which i had to only customize a bit (colors, minor graphic changes etc).

Since that skins are being actively manteined and hotfixed, i created two child skins (one for each) so that i could just inherit the modifications made to the parent skins and keep my customizations.

The problem is that i want my users to be able to choose ONLY my children skins, and atm IPB requires the parent skin to be visible to allow choosing the children skins of that.

I think it would be a greatly useful (and probably fast) change, which avoids having to mess with the main templates with <if> sections to hide certain skins from the selector.

Thanks!
