Instead of the original code scanning for https (which it did not) I
made the version that does an alt code. This should have been done
originally but I did not think about it at the time quite unfortunately.
Still it would be nice to be able to use https with it.
I noted a way that one might be able to get it to work - stunnel, though
it's been years since I've used it so it might not be a solution to the
problem.
Updated .gitignore with files in source/ subdirectory in case configure
is run.
To make sure that make from source/ works I copied the mynx.c to the
source/ directory. I guess I could have updated the configure script but
that seems like it would take more effort than it would be worth.
Format fix README.md.
