Handle core biopsies

[Nicklas Nordborg]

Some patients may have a core biopsy taken at some time (typically a couple of months) before operation. In this case we may receive two sets of specimen under the same scan-b number. There will also be two sets of blood samples under the same number. To distinguish the two cases it has been decided that the barcode for the core biopsy-related forms should have a 'C' as suffix. This need to be handled by the various wizards. The specimen registration wizard should automatically set the BiopsyType=SpecimenCoreBiopsy annotation and the blood registration wizard need a new annotation type: BloodSample=PreNeo, PreOp

Both wizard also need to make sure that specimen and blood items are created with unique names, which means that they need to continue with the usual numerical suffixes from the last used index. Eg. the core biopsies are registered as NNNN.1, NNNN.2, and the regular specimen will then continue NNNN.3, NNNN.4 etc.
