GUIRadioButton: add separate textures for radio image for focus/unfocus states
Use album artist fanart when there is no artist fanart

This is useful especially for albums that are by one main artist but
have some songs featuring other artists, so there may be fanart for "A"
but not "A feat. B".
StringUtils: fix TrimLeft and TrimRight functions with UTF-8 strings
At least on Win32 TrimLeft and TrimRight failed with UTF-8 strings. When dereferencing std::string::iterator through not(ptf_fun(isspace())) character converted to int as signed char (isspace declared as "int isspace(int)").
[WIN32] fixed: check for the error return code instead if XBMC.exe exist. Latter one won't fetch build failures for the other projects.
