Fix shower-max tungsten sens det num.

[sudipbhattarai]

The Shower-max sensitive detector number uses 5 digit numbering format: 7XXYY where XX (01-...) is the parts (volume) number and YY (01-28) is the sector number. This merge has one commit with follwoing changes:

1. All 4 tungstens are now sensitive with numbers (7XXYY) where XX = 01, 03, 05, 07 for first, second, third and fourth tungsten layers.
2. The SD numbering starts from 01 which is beam left closed sector, and the numbers increases in the clockwise manner.
3. The side aluminum web plates dimension is reduced insignificantly (0.5mm) to avoid remoll overlaps.
4. Update shower-max optical simulation matrices.
