Disable configuration of Apache during startup and shutdown since this is no longer a prerequisite for running unit tests, and it seems to be causing problems on the live CI server.

Made bootstrap lighter-weight by creating factories instead of instantiating services during plugin manager initialization.  Now objects are instantiated on demand.

Prefixed plugin manager service names with "VuFind\" as first step toward best-practice naming for global services.

More appropriate abstraction (throw exception instead of dying with non-object error if table manager not assigned).

Changed statistics driver plugin manager to return non-shared instances; eliminated explicit cloning.

Resolved bug in install script: directory structure not correctly initialized when choosing default local directory in interactive mode.  (Resolves VUFIND-697).

Search box cleanup: hide type drop-down if no types are available; removed some unused lines from jquerymobile version.

* tests/unit-tests/src/ILS/Driver/SymphonyTest.php
(testBadBaseUrl): Skip test if PHP version < 5.3.4.

Eliminated [GoogleSearch] setting (search API is now deprecated and should no longer be used -- no reason to support in VuFind 2); created central method for storing warnings in \VuFind\Config\Upgrade (for easier debugging, etc.).

Refactored Auth plugins to avoid dependence on generic ServiceLocatorAwareInterface; injections are now more targeted for clearer dependencies.  Also added some missing comments.

Use explicit dependency injection for ILS authentication module instead of relying on service locator.

  - Eliminated dependency on ServiceLocatorAwareInterface by creating more targeted initWithDriverManager method
  - Added setDriver method to enable more flexible usage/testing
  - Implemented fluent interface on setConfig/setDriver to simplify factory routine
  - Made some methods more tolerant of missing configuration settings
