Enable users to download scores for HTP. phenotypes

[ValWood]

We discussed this after the SAB.
From memory, I think we said that we could enable a column in the download to add the score for a specific phenotype.
This would allow users to download, and sort so that they could
i) choose their own cut-off threshold
ii) reupload their reduced list

How should we include it since a gene can have multiple annotations?
Should we comma separate the values?

vw: I haven't though how this would work but I think it would need to be a by term option because scores will vary by chemical and concentration.

Needs discussion to find a sensible solution
