#102 exif --xml-output should escape field values

[Andras Nagy]

If a field (e.g. XP_Title) value contains a character which is special in xml (e.g. "Joe & Jim" or "Haha :>"), the result might be invalid/unparsable xml. Such characters should be escaped according to XML rules. (E.g. <XP_Title>Joe &amp; Jim</XP_Title> or <XP_Title>Haha :&gt;</XP_Title>.)

Reproable w version 0.6.19.
