Enhancement: Handle paired reads automatically

[schorlton]

Currently, the user has to create a list of dataset paired-end reads manually by dividing the reads for each sample between pair 1 and pair 2. Galaxy automatically does this for the user based on a default rule of _1/_2 or custom rules. This should be implemented in Galaksio

[TKlingstrom]

We have noted the improvement and agree but we are short on programming capacity. We appreciate all help we can get on improving/updating Galaksio and otherwise I think any major work will have to wait until the autumn.
