Add compatibility with AdGuard's #%#//scriptlet(...) syntax
Related issue: - https://github.com/AdguardTeam/Scriptlets/issues/332 Additionally, uBO's own scriplet syntax now also accept quoting the parameters with either `'` or `"`. This can be used to avoid having to escape commas when they are present in a parameter.
