Fixes #33 by changing use of restez_connect() and restez_disconnect(): they are no longer user-facing, and instead get run internally for each instance of connecting to the local database. This prevents extra connections from being created and garbage-collected.
Also:
removes start-up message
updates vignettes and README
reads from db in read-only mode (should allow for multiple simultaneous processes accessing db)
ignores scan = TRUE argument of db_create() if zgrep is not available (i.e., on windows)
