0.14.1

[acheronfail]

Fixes #89

Notable additions:

• Support regular expression capturing groups
  • Refer to named groups (/(?P<name>.)/) with $name or ${name}
  • Refer to any groups with its index, e.g. $1 or ${1}
  • Insert a $ with $$
  • For more on this syntax, read the regex crate's documentation
• When files are detected as having ascii encoding, default to utf8 since it's ascii compatible and more widely used

Remaining work:

• [x] tests for new capturing group behaviour
