Reworked the fmtext format to use in-line formatting. Characters used for formatting are part of Unicode Supplemental Private Area-B, or Plane 16. fmtext no longer need 5x the text space to store formatting information, though they are harder to change at arbitrary points. This was something we hardly ever did anyhow, and we can still do everything we need to do. fmtext keeps a pair of colors and a char for default attributes to be applied when necessary. Searching is now done inline at owl_fmtext_waddstr() rather than specifying a section of the string to be reversed. This probably still needs some cleanup and more comments, but it works.
