OmeroContext is throwing exceptions on missing properties too early.

[jamoore]

The exceptions that client users/developers have been seeing during login are due to the extra call to ApplicationContext.refresh specified by the client/resources/beanRefContext.xml file. If we change this to "false" and perform checks in OmeroContext, then this should go away.

Also, to make this work, we're including all the non-sensitive properties files from /etc in the client jar. This should make things a good deal simpler. At some point, these may need to be removed and put in a omero-etc.jar or similar, but for the moment these things just aren't that variable. All currently important variables can be overwritten with Server & Login.

This is a continuation of #148, and is fixed by r897. Where possible contexts are eagerly loaded; the client context, however cannot be. For that reason, we have to check all contexts for their load status via:

  try { ctx.getBeanFactory(); } 
  catch (IllegalStateException ex) { ctx.refresh(); }

r898 removes a piece of this changeset that will be re-added later.

r912 fixes the omero.rootpass issue by throwing the rootLogin bean out of ome/client/spring.xml and into ome/testing/data.xml

Clients now seem to be able to login without issue. (I.e. without needing to call System.setProperty(...,...). Closing.
