Related to VUFIND-504: truncate the ID list when doing a tag search to avoid MaxBooleanClauses error.
Eliminated RC4 file from vendor directory in favor of moving code inside wrapper class;
the original code no longer seems to be maintained, so it is not composer-friendly.
Created Composer configuration and rearranged vendor directory to match; this should make it easier for people to add additional dependencies (VUFIND-740).
Upgrade to Zend Framework 2.1.3
Fixed inaccurate comment.
Made XSLT importer custom class handling more flexible (and made the nasty class truncation logic optional, so we can start to move away from it).  Updated comments in configuration files to match.
Added missing comments.
Created date converter service; decoupled Holds controller plugin from date converter.
Date converter dependency injection for ILS drivers.
Use simpler object for test.
Inject date converter into view helpers.
Inject Date Converter into Summon record driver.
Pass date converter to assignMetadata rather than creating a new object every time.
Decoupled date converter from config reader.
Updated dependencies.
