property to pluginClass, added call to get entityPackages from plugins.

Fixed bug where if you put in bad info for your smtp server when setting up the app, but later fixed it, it will always start off with the bad info after Tomcat restarts.

Got changes to email prefix and admin email to take effect. Added support for preference change event handlers for notifications events and for handlers that can handle both notifications and site config events.

Added config and init logging to log4j configuration, added more logging to PropertiesConfig to troubleshoot issues with Vagrant VM initialization.

Added preference for how often to check if locked out users should be let back in. Made how to specify time intervals consistent within the User Logins and Session Controls section by having Failed Logins Lockout Duration and User Inactivity Lockout both be entered in Intervals.

Made the alias token timeout checking schedule configurable by the user. Made the inactivity lockout schedule actually take effect without a Tomcat restart. Readded line to SiteConfigPreferenceEvent that got left out of previous commit which was preventing events from working.

Created events for changing site config preferences and updated how often alias token timeout was checked based on timeout interval. Also added sessionTimeout back in.

Modified alias token expiration so the frequency of checking for expiration would depend on the length before timeout. Previously, it would only check every hour, even if timeout was set to 10 minutes. Currently the frequency of checking doesn't change until you restart Tomcat, but I will have it take effect immediately once I create events we can trigger when changing preferences.

updated in the validator if updated in prefs. Changed to wire in prefs
object.

XNAT-4232 Tangentially related, providing more logging info on XAPI execution, logging arc-spec initialization.
