* Fix CRC calculation, add more CRC parameters
Use the Boost CRC module to calculate the CRC values.
Add options for final xor value, reflectIn and reflectOut.
Fixes#320
* Cleanup Hash view combo box, add CRC8
* Use offset/size consistently
* Cleanup: unify processing data by chunks
* Change CRC algorithm back, drop boost dependency
This is mostly the original algorithm, with a few fixes and small
additions (support for reflect In / Out, final XOR value).
* Use size_t for file read size consistently
