E and T Morse code patterns incorrect

[MarkWoodworth]

It is only a test stub so this is just a quibble, but the Morse demonstration code misstates the codes for E and T. In reality, E is a DIT, and T is a DAH.

[MarkWoodworth]

Also (again a quibble that is off the real point of the code), the emergency SOS is not the three letters S O S, but is a single character (a prosign) of three dits three dahs three dits with no inter-letter spacing.
