mail body is badly quoted-printable encoded => accents issues

src/grouper/edu/internet2/middleware/grouper/util/GrouperEmail.java does:

message.setContent(this.body, "text/plain");

which is should be

message.setContent(this.body, "text/plain; charset=utf-8");

otherwise the accents are broken

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

Test =E9

when it should be

Test =C3=A9
