Add display of constructs for fly and worm donors

Someone might want to look through my changes to views.py, as well as the human_donor.json and mouse_donor.json schemas.
Correct letter casing for worm/fly construct title
Merge remote-tracking branch 'origin/master' into 1187-donor-const
Merge remote-tracking branch 'origin/uniprot-fix' into 1187-donor-const
Remove genomic_alterations

Changed human_donor.json and mouse_donor.json back to what they were, without genomic_alterations.
Merge remote-tracking branch 'origin/master' into 1187-donor-const
Remove genomic_alterations mixins from human and mouse donors
Add model_organism_donor_constructs calculated property
Add model_organism_donor_constructs calculated property
Merge branch '1187-donor-const' of https://github.com/ENCODE-DCC/encoded into 1187-donor-const
Add model_organism_donor_construct calculated property to biosample
Fixed model_organism_donor_constructs embedding in biosample
Display fly/worm donor constructs from calc fields

Now using the new model_organism_donor_constructs field to display fly and worm donor constructs, while still using constructs for human donors.
Add donor_characterizations to loadxl and test data
Merge branch '1187-donor-const' of https://github.com/ENCODE-DCC/encoded into 1187-donor-const
Separate donor information to its own panel

Still needs cleanup for characterizations, and experiment Jest test needs to be redone. Temporarily removed many tests from experiments-test.js; will redo and restore later.
Fix fly donor to pass test_html_pages
Merge remote-tracking branch 'origin/master' into 1187-donor-const
Complete donor characterization display

Allow documents to be displayed with panel classes for all but donor_characterizations. Embed fields to display donor characterization details.
Restore experiment Jest test

Removed non-working parts of Experiment Jest in earlier commits because of incomplete document display changes. Completed the changes in the last commit, so restoring the Jest test here. Also fixed a flaw in the award test data.
