Main project script sets executable flags at configure time

Until now, when the project's source was downloaded from something like
arXiv, in `README.md', we were instructing them to set the executable flags
of all the files that need it. But except for `./project', the reader
shouldn't have to worry about the project internals! Once its executable,
`./project' can easily fix the executable flags of all the files that need
it automatically.

With this commit, in `README.md', we just instruct the reader to set the
executable flag of `./project' and any other file that needs an executable
flag is given one at the start of the set of commands for `./project
configure'. In customized projects, if an author needs executable flags on
any other files, they can easily add it there without involving the user.
