Change way stream blocks are computed to maximize compression.

* Add Dictionary Size computation and setting capability.
* Remove 7/9 scaling for lzma levels. Default still 5.
* LZMA levels now 1-9.
* Improve info displays.
* Assembler will now select either nasm or yasm.
* ETA will be displayed after each chunk is processed.
* Decompression status updated every 5 seconds or so.
* Documentation updates.
* Code cleanups (whitespace removal, comment alignment).
