Add support for cp1252 (Western European) codepage.

Browse source 
In Europe Windows defaults to its own codepage cp1252 (also known as "WinLatin"
or "Windows-1252"). cp1252 adds some characters to ISO-8859-1.

Some mp3 tagging software on Windows uses cp1252 instead of ISO-8859-1. This
violates the ID3 specification, which requires tags to be ISO-8859-1 or
Unicode. However, similar violations are made for other codepages and supported
by Rockbox using the "Default Codepage" setting. Add support for cp1252 to
enable people using such broken tools to override the correct decoding to get
their tags displayed properly.
