reroute keyword/value completion

From /api/v1/completion, old to new:
  * annotation/<keyword> -> annotation-keyworld/<keyword>
  * annotation/<keyword>/<val> -> annotation-value/<keyword>/<val>
  * namespace/<keyword> -> namespace-keyword/<keyword>
  * namespace/<keyword>/<val> -> namespace-value/<keyword>/<val>
REST documentation fix
correct perms on java source
correct perms on rst source
capitalize translation
add synonyms data
towards completion of values across all namespaces
fix perms on rest source
support slow loading synonyms to MongoDB
synonym load; annotate heavy I/O section

This is a great candidate for applying a threaded approach to decrease
the amount of time it takes to load synonym data.
relocate mongo-check main to subdir
bump MongoDB indexes in nsvalues
defer write-heavy I/O to a couple threads
go.sh; swap load/check order
mongo-check.sh; use mongo_check subdir
synonym load; one thread is fine
README.rst; license
bump README.rst
README.rst; swap check/load
core.clj load; remove vice drop
