Features should have an uninstall tab like the module management screen

When you disable a feature module, there are still module/components values in the features_codecache store.... I think these are kept to protect against overwriting current values and to make this act similar to a module disable action.

However, there are times when you want to start totally fresh. Either for development testing or to force a rebuild with a new version of a feature.

It would not be hard to add an "Uninstall Features" tab to the admin screen that would be a check box list all disabled features. The action would be to remove all modules/component entries from the features_codecache store.
