Add Xcode Beta Symlinking/Renaming Options

[jsorge]

Tell us how we can improve Xcodes When working with Xcode betas, it would be great to have 2 new things (which are related I think):

1. The ability to rename the betas to Xcode-beta.app just like they are when downloaded from the dev portal.2.
2. The ability to symlink an Xcode beta as Xcode-beta.app.3.

The motivation for this would be to aid in tooling which can target either Xcode production (which should still be Xcode.app) and Xcode betas (for things like this Xcode beta simulator fix).

What would you like to see? How would you like it to work?

I think this could be pulled off a couple of ways: have a new section in the preferences related to Xcode betas specifically, or add an option in the Active/Select section of the advanced preferences to symlink to the Xcode betas. In addition, right clicking on a beta would display an additional menu item to create a symlink for a beta version when one is selected. I don't think getting rid of the Xcode.app symlink is right since some people may still want to do that to test their workflows with a beta version.
