Clarify allow/warn/deny. Remove enable/disable.

Browse Source 
Disable and enable when not specifically explained were not clear to me
as an English language speaker, but I was able to figure it out fairly
easily due to the examples having A/W, which I assumed meant `allow` and
`warn`.  I removed both words to be sure it was clear as well as
extending the note on what deny means.  It now includes a statement on
exactly what each word means.

* `allow`/`warn`/`deny` can be limited to a single function or module using `#[allow(...)]`, etc.
Note: `deny` produces errors instead of warnings.
Note: `allow` in this case means to "allow your code to have the lint without
warning". `deny` means "produce an error if your code has the lint". `warn`
means "produce a warning, but don't produce an error due to this lint". An
error causes clippy to exit with an error code, so is useful in scripts like
CI/CD.
If you do not want to include your lint levels in your code, you can globally enable/disable lints
