[Therion] epsg:3794 - PROJ4 library: -1 (no arguments in initialization list)

[Rhys Tyers]

Sorry for the spam but I have solved this issue. I probably messed up my
libproj install somehow so just a reinstall allowed me to build Therion.

sudo apt --purge remove libproj-dev
sudo apt install  libproj-dev

I also had to install libwxgtk3.0-gtk3-dev instead of libwxgtk3.0-dev
mentioned in the docs, so perhaps that package name has changed in Ubuntu
20.04 (unrelated to my issue though).

Latest Therion builds the config file. All is well.
