Update some of the 2000 README.md files

I am aware of some entries that do not compile that I haven't even
thought about fixing yet.

I also need to use my linux box to test the X11 entries (this goes for
other years as well) but that'll come at another time as I rarely am at
sitting at that computer. But the README.md files should be in a better
state.
