[UI] Enhancer-Gene Predictions tables

[engreitz]

Some small changes / questions regarding the Enhancer-Gene Predictions table on the Gene, Variant, and Region pages:

1. The 'Cell Type' column seems to have lost its capitalization (it's all lower case). It's not that way in the original predictions, I believe. Did this happen in the UI, or in the KG?

2. The 'Model' column should be 'ENCODE-rE2G', not 'ENCODE' (gene page) or 'ENCODE-E2G-DNaseOnly' (variant + region pages). Again, is this happening in the UI, or in the KG?

3. The 'Distance (Enhancer to Gene)' should ideally be replaced with 'Distance (Enhancer to Gene TSS)', which hopefully is another feature loaded into the KG?

4. Small documentation tweak: The text for the mouse-over documentation of the table title should have a newline added before 'See Documentation'

5. On the Enhancer-Gene Predictions table on the Variant page, the 'Dataset' column should be filled with an encode id e.g. 'ENC149285XYZ' with a hyperlink (rather than 'files' with a hyperlink), as in the Enhancer-Gene Predictions table on the Gene page

6. On the Regions page, the 'Enhancer Chromosome, 'Enhancer Start', and "Enhancer Start' columns could be consolidated into a single column 'Enhancer Coordinates', with values e.g. 'chr10:105-106' created by concatenating this info

@engreitz @shaneliu0 we recently changed the backend so element-gene (and other edges) should have both a "source" (in this case ENCODE) and a "method" which is currently ("element gene regulatory interaction predictions using Distal regulation ENCODE-rE2G") (synthesized from ENCODE metadata)

@hitz So is it correct that there is no field in the backend that would just return 'ENCODE-rE2G'? I think that is probably important. I guess for now we could manually code it as 'ENCODE-rE2G' in the front-end but that is going to break as soon as we get other models in here (which might already be the case).

Alternatively, I guess we could change the names of the Columns in the UI to separately show "Source" (in place of the current 'Model' column) and "Method" (as an additional column at the far right)

[hitz]

We can change the longer method to a shorter one, but we have to reload etc. We need to review all of these and we can fix them altogether.
