Fixed several issues: stable 64 bit support, archives with 0 files, #3743.
Ported for 9.04: XZ compression format, LZMA2 method (in my personal opinion, faster, more compact and advanced).
Ported for 9.06: extraction from exe, elf, swf, flv and mslz.
7z.dll is now included in SevenZipSharp assembly and source code. It is custom built by me - I changed four compiler options: "Maximize Speed (/O2"), "Intrinsic Functions (/Oi)", "Favor Fast Code (/Ot)" and "Enable link-time code generation (/GL)". The library increased by 200 kb in size but became 5-7% faster (based on my measures). In other words, I tried to "overclock" it.
SevenZipCompressor has two new properties. The first is DefaultItemName to set the default name in stream compression (regarding MemoryStream compression issue). The second is FastCompression, it switches off any event notifications but compression becomes 15% faster. In future releases, the speed will continue to increase.
Multi volume archives are now can be checked for integrity with Check() method, useful exceptions being thrown in case of specific errors.
