task pages: Moved many NGS packages from bio to bio-ngs

[Steffen Möller <smoesmoesmoe@gmail.com>]

Hello,

This effort is a bit moot since we should likely follow one of the
classifications that are already out there (like EDAM ontology topics or
OMICtools categories), but this will take some time. So, I finally got
around to manually moving a series of NGS-centric packages over to the
bio-ngs task. I have no exact clue about how quickly the task pages will
be updated, just possibly give it a check tomorrow about what I have
missed or about where I was too ambitious while doing the transfer.

Cheers,

Steffen
