title: set thread count for quartz thread pool
body: <p>I have created file <code>quartz.properties</code> and put it in classpath.
  The properties are</p>
  
  <pre><code>org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
  org.quartz.threadPool.threadCount = 1
  </code></pre>
  
  <p>But when I start the application I get this message</p>
  
  <pre><code>Scheduler class: 'org.quartz.core.QuartzScheduler' - running locally.
  NOT STARTED.
  Currently in standby mode.
  Number of jobs executed: 0
  Using thread pool 'org.quartz.simpl.SimpleThreadPool' - with 10 threads.
  Using job-store 'org.quartz.simpl.RAMJobStore' - which does not support persistence. and is not clustered.
  </code></pre>
  
  <p>Does it load property or no? I run only one thread for scheduler anyway...</p>
