    Fix decoding of tab-indented 'charset' of multi-part MIME text parts

    Apple Mail apparently uses tabs to indent the charset of nested MIME parts:

    e.g.
    --Apple-Mail-143B9F0C-6BB4-4C8E-869B-6DE05D6B58CE
    Content-Type: text/plain;
    <tab>charset=utf-8
    Content-Transfer-Encoding: quoted-printable

    This fixes issue #483 reported by Nelgin

    Log Message:
    Support non-quoted MIME Content-type boundary parameters (semicolon delimited)

    This should fix issue #559, for example:
    Content-Type: multipart/alternative;
    boundary=mk3-ebfa33c1cd454cc2b1c618f5d74b41af; charset=UTF-8

    We were assuming all boundary parameter values are quoted (apparently not
    true, see https://www.rfc-editor.org/rfc/rfc2046#section-5.1.1) - so support non-quoted boundary values which also may have a semicolon delimiter.

    Also, truncate any white-space from a boundary value (shouldn't be there per RFC2046).
