Parse IRC formatting in timestamp string

Strip formatting when calculating the timestamp width to avoid
moving a bunch of code around. Use styleAdd (now with an initial
style parameter) to show timestamps.

This allows changing the style of the timestamps from the default
gray using literal IRC formatting codes in the string. Not ideal,
but no new options needed.

Suggested by Hoël Bézier and Sebastian LaVine.
