[Opensource] Controller.getLogger()

[larry hamel]

Expresso has a lot of duplicated code for creating loggers (log4j Category's) for each controller.  

Now there is a simple superclass method in Controller.java, getLogger(), which will create a logger with the name of the subclass on demand.  So instead of duplicating setupLog() code in each and every Controller you write, just do logging like

getLogger().error("blah");
getLogger().debug("blah");

which will create a logger the first time and reuse it thereafter.

p.s. Mike, I added a 5.1 release tag to the changelog; let me know if this was inappropriate
