Release 2.26.6

• Simplify itb_pango.py: don’t use ctypes, use from gi.repository import Pango instead
• Get more information about the Pango rendering support for an emoji and use fallback in emoji-picker only when necessary (Resolves: #508)
• Also make it possible to show font file names, font versions, and emoji related OpenType tables of the fonts used (shown only in debug mode, i.e. when "emoji-picker --debug" is used, when not in debug mode show only the font family name)
• In do_reset() skip clearing input only when the surrounding text up to the cursor ends with the current preedit (Resolves: #529)
• Translation update from Weblate (kab 75.9%)
