FireVoxel Build 398 is released.

1. Developed a compression scheme for the pseudo-real volumes (Signed integer volumes represented as REAL).  Compression 1:1 matches the corresponding ratios for SINT files.

2. Removed the DICOM load dialog for choosing between the REAL load and UINT load with the bias. Loading of CT files is now done the same way as Mango and 3DSlicer.

3. Rigid HU display on the status bar is removed and HU units are properly displayed.

4. IsMatchingVolume function : extended for quasi-precise comparison with MaxAbsDiff measure and specified Eps tolerance.
