- liblzma source code added (we don't want to use a DLL) - Moved lzma.h and lzma subfolder to api subfolder - Removed some unnecessary files (liblzma.def, lzma_dll.txt) - Adjusted make.bat, added some "echo" statements to show build state. - Can be compiled, but using "-cl" or "-cx" give errors (specified filter chain is not supported), "-cm" gives a crash
