Added MS Macintosh Code Page Support

Microsoft applications recognize the following code page numbers for Mac CPs:

10000   Macintosh Roman
10006   Macintosh Greek
10007   Macintosh Cyrillic
10029   Macintosh Central Europe <-- Added in this commit
10079   Macintosh Icelandic
10081   Macintosh Turkish

Note that the ICONV binary on OSX doesn't recognize these codes.

http://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/ has the relevant defs

The CENTEURO.TXT file was used to generate the missing Central Europe codepage
Merge pull request #23 from Niggler/master
