Fixed issue with color markers in messages sent to the client.

This fix eliminates crashes related to color markers being at end-of-line, and also makes colors persist across line breaks.

- The broadcast message is split up in multiple packets, one per line
- Color markers are reorganized, so that color 'sticks across lines'
- The wrapping method calculates the *rendered* line length. Thus, if the user has a weird font, it might look weird.
