Changed fNbt and fNbt.Test framework requirements back to .NET 3.5 Client Profile (in anticipation of 0.6.1 bugfix release)
NbtFile.LoadFromFile(...) and LoadFromBuffer(...) now return 'long' instead of 'int' and accurately report bytes-read for files/buffers over 2 GiB in size.
Updated Doxyfile to Doxygen 1.8.7
Updated Readme and Changelog
Updated a few unit tests to reflect recent NbtFile API change.
0.6.1 release done! Updated the license file.
