Added paradox for list-packages alternative with perspectives support

I am having trouble making these layers lightweight though... they add 0.3 seconds to startup, any tips on how to use `use-package` ?
Try adding `:defer t`, if this package supports autoloads properly, that should get rid of the load time hit. If you do this you will need to change the `:config` section into an `:init` section. For deferred packages, init runs immediately so that you can bind keys that will activate it, whereas config runs after it is lazily loaded. For non-deferred packages they do the same thing.
