DefaultSecurityConfiguration.getInstance causes NullPointerException when ESAPI.properties doesn't exist

What steps will reproduce the problem?
1. I stumbled across this while calling static methods on ELEncodeFunctions, 
but it seems like it would affect anything that uses ObjFactory to get a 
SecurityConfiguration.
Putting a blank ESAPI.properties file on the classpath makes it work.

What is the expected output? What do you see instead?
Ideally I shouldn't need to set up an empty properties file just to be able to 
use basic (html/javascript/whatever)-escaping. If you insist on a properties 
file, at least make it do something useful when it can't load its config 
instead of logging a warning and then going down a code path that is guaranteed 
to cause an NPE.

What version of the product are you using? On what operating system?
2.0_rc10

Does this issue affect only a specified browser or set of browsers?
Not browser-specific

Please provide any additional information below.

Here's the stack trace (including a little bit of context from using the static 
methods via EL):
