GtkHTML显示
GtkHTML控件就可以显示HTML，Evolution就是用的这个。
1. gtk_html_begin_content(), then gtk_html_write(), at last gtk_html_end().
2. gtk_html_set_base(), gtk_html_jump_to_anchor(), gtk_html_load_empty().
3. Contructor: gtk_html_new()
Signals:
“url-requested“
“obj-requested“ (embedded objects)
“load-done“
“submit“
“size-changed“
“link-clicked“
“button-press-event“
“redirect“
“title-changed“
“on-url“
