Expose standard system properties in a better way

[GoogleCodeExporter]

Java has a standard set of system properties that are always available:

http://docs.oracle.com/javase/7/docs/api/java/lang/System.html#getProperties()

This is problematic for a number of reasons:

1) Using strings everywhere rather than constants
2) Accessing them generically via a map rather than specific getters for each 
property
3) Using the static global System object doesn't allow changing the values in 
tests

It would be nice to have a set of constants for all the properties and an API 
with getters like getUserHome, getTemporaryDirectory, etc.

Tentative +1. I'll bring it up in our next API meeting.

We're going to go ahead w/ a class called StandardSystemProperties that 
contains these string constants.
