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.
