Version 0.4

• Reworked word selection so that a game consists of all words in a random ordering (versus the earlier system of randomly picking a word from the list on each new word)
• Allow players to enter a seed code for a game, this permits multiple players to play the same sequence of words by using the same seed code
• Allow players to share their results for a given code + word without giving away the word
• Internal changes - refactoring, unit testing, unit test coverage
