move some file encodings to UTF-8
* THANKS, doc/ChangeLog-2011, tests/ChangeLog-2011, tests/gpg/geheim.txt: convert from iso 8859-1 to utf-8. * lang/qt/src/dataprovider.cpp, lang/qt/src/qgpgmerefreshkeysjob.cpp, lang/qt/src/qgpgmesecretkeyexportjob.cpp: replace U+FFFD REPLACEMENT CHARACTER with proper U+00E4 LATIN SMALL LETTER A WITH DIAERESIS.
Note that src/versioninfo.rc.in is still ISO-8859-1. I don't know
whether Windows will properly handle UTF-8 in this file or not, so i
have not touched it.
