Use a single template file for variant/result templated data

I tried to put these into views within cell.coffee but they are used in the details modal as well so it was easier to just go back to using the original varify method of using a bunch of template methods in a single templates file. This can be changed later but this way allows for the easiest reuse in the details modal.
Remove the rootUrl from options, it is a utility method now
Initial script and html for showing the details modal

This is a long way from done but I want to get these files in an tracking so I can follow my changes
Add missing parenthesis after call to getRootUrl in utils
Populate variant details tab when modal is shown

The assessment data is still not functioning correctly but this includes the variant/result details, basically, half the modal window display
Remove details template as all html is generated in view
Add CSS for assessment table in variant details tab of result modal
Add missing trailing / to fix redirect on initial request
Update the latest internal changes of variants/resources.py
Fetch metrics on render and update no assessments message to be muted
Add the initial code for the assessments tab

The tab displays and is workable. Have not fully tested and there are some styling issues remaining.
Add styling for incidental findings indicator
Manually set the event handlers on error close and radio buttons
Add code to support saving assessments via the knowledge capture tab

As far as I know, the functionality of the original varify result modal is fully replicated as of this commit.
Remove unnecessary comma in define
Use shorter variable names and fix initializer for assessment data
Merge pull request #27 from cbmi/variant-details-modal

Fully replicate the result modal from the internal version
