Implement support for library preparation that uses Illumina Unique Dual indexes

[Nicklas Nordborg]

The current library preparation pipeline only support the TruSeqSingle barcodes (with names starting with AD) and pool layouts are hard-coded into the various wizards.

Since we already have support for other barcode types in other places it should be possible to do something like this:

• Assign a BarcodeSet annotation to a library preparation protocol. If not specified we use the TruSeqSingle as default.
• Pool layouts still need to be coded into the wizards, but they should now also be able to use barcodes from the actual BarcodeSet.
• The "Create flow cell" wizard must support a second index read and default values depend on the barcode length.
• Maybe something more...
