Reads intensities considerations

[douweschulte]

Right now the peaks reads scale between [1-2] this could be changed to [0-1] to allow for a broader separation between reads with highly different areas. As there are not very often datasets with Fasta/simple and peaks data at once the old argument of the peaks reads needing to have a higher score than the other reads does not really hold.
Besides this it is also interesting to think a bit better on how to normalize the scores. Now the score is absolute but there can be made some points that a normalized scoring (the best is always 1) is beneficial. Although it then has to be seen if this does not introduce too big of a problem when changing the cutoff scores in the batchfile.

As it did not influence anything in the scores this change will be kept.
