Button to reset skin to blank (Default) in the Launcher skin menu

The Java website profile page has a option to reset your skin back to default but the launcher doesn't have this (nor the option to apply capes to the default skin, you have to go to the website after putting on the default skin to add a cape to it). The website profile lacks the default skins to change to which the launcher has.

Adding that button to the launcher means we wouldn't have to go to the website but we can go to either one.
