Alert service should send out alerts on a configurable schedule

(In [525]) re #118 Setup MasterWebAppListener? to allow web-apps to register own listeners without needing to modify their web.xml. Moved listener that initialized models to run from master via topaz-common-config.xml.

Final step is to write code to initialize alerts via its topaz-config.xml.

(In [532]) re #118 Implementation to send out alerts on configurable schedule

Adds the quartz scheduler to the base-webapp and reads configuration for the scheduler and its jobs from topaz's configuration.

This still requires the web.xml merge in the alerts webservice to close and test #118.

(In [542]) fixes #118 send alerts on a schedule

Mostly this just removes web.xml in favor of base-ws-webapp's web.xml per [427]. That was the only thing missing to making this work.

How to test

Not sure how to write an integration test for this. So just modify alerts/ws-webapp/src/main/webapp/WEB-INF/topaz-config.xml to send alerts every minute. (Set cron to "0 * * * * ?".) Run the integration tests and notice that every minute on the minute, an attempt is made to send out all alerts. Logging level of INFO is required. (It is possible depending on timing that doing this will break the integration test as the job will send out an alert that an integration test was expecting to send out. It'd be fairly rare - like amost never, however, for this to happen.)
