[Texmacs-dev] GNU Guile 3.0.0 released and some suggestions for future GNU TeXmacs

[Darcy Shen]

see https://lists.gnu.org/archive/html/guile-user/2020-01/msg00090.html

I suggest:

- For GNU TeXmacs 3.x, upgrade to Guile 3.x

- For GNU TeXmacs 2.x, we stick to Guile 1.8

- For Python, we upgrade to 3.x and drop 2.x support for GNU TeXmacs 2.x 
and later

- For Qt, we upgrade to 5.x and drop 4.x support for GNU TeXmacs 2.x and 
later
