v1.0b3

• Hopefully fixes #3, #4, #5 and #6, but since moving to coordinated file access, its anyones game.
• Work towards fixing #7.
• Start of code tidy/sanitisation now we've successfully gotten past 'proof-of-concept' phase, which means regressions I'm sure...
• New Chatomatic URL Note: If you have manually changed your URL, it may need fixing to: https://chatomatic.tomcowland.com/?room={room}&name={name}.
• Sync conflict files should now be ignored.
