Fixed Changes:

Browse Source 
- The bit value when in two's compliment mode is not right, it should be on the same line, not wrapped
- The random button should glow when the random function is running, it shouldn't be solid green all the time
- The reset button, can you make the background of it red when hovered over too? I want it to pulse red on the background as well
- Make the title of this page (in head) "Binary Simulator"
- Reinstate the BaseLayout layout which we created previously
- The shifts for Two's Compliment do not work. An Arithmetic Right Shift would keep the value of the most significant bit.
