In absence of explicit declaration, resource compiler uses system
codepage. When this codepage is DBCS or UTF-8, Python's copyright
string is corrupted, because it contains copyright sign encoded
as \xA9.
The fix is to explicitly declare codepage 1252.
Remove auto-generated resource header. Pass definitions required
by resource files (ORIGINAL_FILENAME and FIELD3) directly to resource
compiler.
Remove unused MS_DLL_ID resource string and related dead code.
