barcoding information

[thomasmanke]

information of barcoding is obtained from diverse source json*report, SampleSheet
and passed through a series of confusing and convoluted entires in config[]. This should be tidied up.

Proposal: there should be at most two entries:

• config['info_dict']['barcoding'] = True/False
• config['info_dict']['barcoding_kit']= None/"kit_name"
  possibly one entry could be sufficient

(A solution will likely require a different way to pass config[] between functions)
