Restored calculateQRS_score_LBB() to previous behaviour. (Like No
Confounders, but with threshold adjustments)

Updated the output based on feedback from Tobias.
Schiller files now output all conduction type data on one very long row.
The previous verions output one row per conduction type.

Initial working version of Strauss/Selvester QRS-Score as a standardized
web service (Type2).
