* Reworked query.js to know the difference between date search and advanced searching.
Exposed cdx api's through the query html page
- from, to
- matchType
- filter
Added more appealing styling to the error, index, not-found, query, and search templates
Updated the included jquery and boostrap static files to jQuery v3.3.1, Bootstrap v4.1.3
Implemented optionally using a web worker for making the cdx api request and processing the results
Documented the code
* ensure the display count str function uses the correct "first" value
* added view all captures for an result displayed in the advanced results view
query worker now sends over the recordCount as an integer and as a formatted string
moved the search button to the right after advanced options
* tests: fixed test_intergration.py:test_static_nested_dir failing due to updates
Existing JS files in this repo use Python-esque spacing
