Fix sole_raw_text to allow $

[cubeguerrero]

Changes

Changes the regex expression:
from: ~r/^[^\n$]+/
to: ~r/^[^\n]+$/

The former matches the $ literally, while the new change will asserts position at the end of the string, or before the line terminator right at the end of the string (if any)

Issues

Fixes #7

Maintainers and owner should review OWASP regex best practices to avoid unintentionally adding a CVE-worthy flaw here or elsewhere, because $ in a character set is not a non-terminal. Also, prefer \A and \z unless input is trusted and there a specific need to match only on one line.

Sorry this took a while, I'll be releasing this as 0.9.0 soon.

Also, thanks for the regexp advice @steakknife! AFAIK we should be good with $ in here.
