main.cpp: add a better description on the default / endpoint

ThomasDevoogdt · ThomasDevoogdt · commit 93f257436585 · 2020-10-11T18:20:55.000+02:00
Mainly for debugging, it's better to have all info on the default page. Later, more stuff will be added. Eventually some fill-in form for the post API.
