Switched to DEFLATE instead of LZMA for model object compression.
   This may solve out of memory errors, but I remain worried about memory usage in general (+ the fact we will use LZMA compression in transmission as well).
Also moved compression classes to shared package, + some improvements on LZMA2Compressor itself.

Model: object (de)serialisation & (de)compression now only uses streams (avoiding allocation of byte[] for uncompressed serialised object), this hopefully brings memory usage down a bit more
