License Change to MIT

Hi,

I welcome the recent license change to the MIT License.

However, our lawyer is not yet convinced that the license change is legally "clean".

Could you confirm that:

1. No legacy code originating from the Java GNU ClassPath project remains
   • I could not find any clear statement or indication that all that code has been replaced in the meantime...
   • Alternatively, the original copyright olders (FSF or contributors) could confirm to the relicensing...
     
2. All contributors have agreed to relicense under MIT (this seems to be very likely according to https://github.com/icsharpcode/SharpZipLib/issues/103 and https://github.com/icsharpcode/SharpZipLib/pull/101)
   

Btw, the homepage http://icsharpcode.github.io/SharpZipLib/ still carries the old license, can anyone upate it?

Thanks!
