CTS UI tweaks

[GoogleCodeExporter]

Now that we have a working prototype of the CTS, need to look at it and decide 
on any UI tweaks that we want to make.

Maybe we will want to add some status messages to the display so the user knows 
that the message was successfully submitted.

Also need to decide if the color-cycling is happening at the right point. Mike 
mentioned once he wanted the colors to cycle when the device is in the 
standby/waiting state, but it looks like it's currently happening in another 
state.

Need to improve button scan performance.  It is sluggish right now.  
Investigate removing software debounce.

Add appropriate message displays.  This is my plan:

When idle (after reset):

|      CRACK     |
|    THE  SAFE   | (with color cycling bg)

If user presses a button before starting the challenge:

|       Hey!     | (with flashing bg)
|  Scan QR Code  | (revert back to idle state after a few seconds)

When starting challenge:

|Enter code:     |
|    00 00 00    | (with steady bg)

After first click on SELECT:

|2nd ENTER Sends |
|    12 34 56    | (with rapid flashing (Danger!) bg)

After second click on SELECT:

|=Code Submitted=|
|    12 34 56    | (with steady bg (green for success?))

Added new message displays.

Added pre-input state (Hey!).

Tweaked some colors and blink rates.

Still to do:  Improve button click rate.

Removed software debounce, which improves button click rate and gives 
auto-repeat behavior.

Also made sure cursor is displayed when entering INPUT mode from IDLE or 
SUBMITTING mode.

See the attached state diagram.
