Message:
UTF-8 - first pass

unicode changes:
* remove downstr() from text.c, replace on site with calls to g_utf8_strdown.
  In place downcasing is not a good idea, so the downstr() contract is unfulfillable.

* make owl_text_truncate_cols() and owl_fmtext_truncate_cols() understand character width.
  This may need more work. Some code duplication - see if we can refactor.

* stristr() rewritten to yse g_utf_casefold() instead of downstr(), and restructured to have a single return.

* only_whitespace() rewritten for unicode.

glib changes:
* rewrite owl_sprintf() in terms of g_strdup_vprintf()

WARNING: THIS IS NOT SAFE YET. Network data is not yet sanitized. Non
UTF-8 inputs may do horrible things to you. This phase is just
working on rendering.
