Better handling of quote terms, fix bug in handling of longer queries.
...
... where some terms may previously have been ignored. The latter bug was due to the handling of QueryHeads with AnyOf-style predicates interacting poorly with alreadyConsideredTerms in SearchIndex.java

Fix bugs related to search result selection in the case with multiple search terms.
...
* A deduplication filter step ran too early, and removed many good results on the basis that they partially, but did not fully fit another set of search terms.
* Altered the query creation process to prefer documents where multiple terms appear in the priority index.

"-Dsmall-ram=TRUE" no longer does anything. Remove references to the flag, which previously reduced the memory footprint of the loader and index service.

Break apart reverse index into a separate full index and priority index. It did this before using the same code. This will make the priority index about half as big since it no longer needs to keep metadata.

Gradle shouldn't generate dist zips, zipping jar files is slow and also just ridiculous when you realize jar files are zip files and you can't compress a file twice using the same algo.
