Make lolcat easier to use

[nazmulidris]

Provide a constructor where the following is specified

1. the initial seed
2. the speed at which the colorwheel changes

Provide a method to manipulate the seed easily

1. have meaningful enums for rapid or slow change of seed

In the dialog editor make sure to have a lolcat init'd w/ the same seed so that it doesn't change every time the app is run
