Maintenance update

As the title suggest, this is not a big update and does not introduce any new features. The opposite is true, as those custom install and uninstall scripts are removed and the Readme file is no longer converted to HTML. This reduces a little bit of complexity and dependency.

Speaking of dependency, the internal libraries it depends on are all updated. The most notable one is the argument parser called clap, which is now at version 4.5 and no longer outputs the help in colors. Otherwise a few lines are refactored or reformatted and the README.md is worded differently; at some places. Overall this is a small update to bring the underlying code to the current state of the art. And to find an excuse to compile it with the most recent Rust compiler. If you liked the previous version of this program, then you will most likely like it again.

enjoy_0.5.0.tar.gz is the release package to download and extract. enjoyd.gz is the debug build and not intended for normal usage. You can also install from crates.io with cargo install enjoy. Usually I wait a few days or maybe a week before updating there.
