Rockbox Utility: fix proxy password getting lost (FS#12166).

The proxy settings are stored as string representation in the configuration
file. If username / password contains characters used as separators parsing the
string again will cause wrong results. Percent-encode them before storing, and
parse it as percent-encoded string when reading it back.
