[Hexchat] Add font rendering patch
- Added "Use pango_font_metrics_get_height() to calculate font height" patch. Upstream bug.
I did notice an improvement in font rendering with this patch applied while testing the now abandoned D10958, so I think it's deserving of being fixed. Notably chat seems less "smooshed" with a more natural spacing between lines.
- Tested that Hexchat opened
- Checked that IRC was working
- Checked that font appeared to be rendering acceptably
