Added three buttons that currently just move the mouse to either Start or Practice button in Hearthstone Window
For now, only supports Hearthstone running in Windowed mode at 1024x768

TODO:
1. Fix the BotSuite.Mouse.LeftClick() call, it is throwing an exception
2. Fix the PictureBox in the Form to be able to display the screenshot we are taking of the hearthstone window every frame.
