better handling of error conditions in all BuildFromXML methods, per comment:
// BuildFromXML methods should always return a BlockFile, not NULL,
// even if the result is flawed (e.g., refers to nonexistent file),
// as testing will be done in DirManager::ProjectFSCK().
better handling of error conditions in PCMAliasBlockFile::BuildFromXML so that DirManager::ProjectFSCK can report cases of missing PCMAliasBlockFile files on opening projects where missing files were not corrected
code cleanup
naming improvements for clarity (e.g., aliasedFileName instead of aliasedFile for an instance of wxFileName -- it's not an instance of AliasedFile)
parens, not square brackets, for parenthetic phrases
Basic problem was in using wxConvUTF8 instead of wxConvFile. I believe wxConvFile should work on all platforms, but if not we can "#ifdef _WIN32" its use.
Also simplified the code by getting rid of the mFileNameChar member. It was used only in ODPCMAliasBlockFile::WriteSummary() so there's no reason to do the conversion from mFileName in so many places -- just do it once, in ODPCMAliasBlockFile::WriteSummary().
Also some minor refactoring.
This feature works with mp3 right now - may work on other formats, but that will be a seperate commit.
It is not enabled so most of the changes won't even be compiled, and those that do won't be run.
To enable it uncommment the EXPERIMENTAL_ODFFMPEG def in Experimental.h
