Removed wxMMedia
Added wxMMedia2: it should work on linux (wave read/write, aiff read only)
I begin to write windows driver now
Added some file to filelist.txt
Make configure build wxMMedia2 makefiles
git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@3381 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
