Convenient way to set shindig.host and shindig.port in web.xml

In addition to specifying the shindig.host -Dshindig.host=`hostname`  to your server startup script. This patch allows users a way to conveniently select a shindig.host and shindig.port that shindig WAR is deployed on from a specified list in the web.xml <context-param/>

Sorry for the multi posts, was having a bit of problem getting the right patch
in.
In this update, we should be able to set any system property by adding a
system.properties <param-value> in the web.xml
I documented a few param or VM arguments that can be set for Shindig in the
web.xml, please feel free to update the list.

Added code to check for empty System Properties list from the web.xml

for some reason I can't comment on individual code chunks.  Here are some
suggestions:
* Use shindig code-style, 2 space indents, no tabs.
* When doing the 2nd StringUtils.split (on =) use a limit of 2 to simplify the
code.  Right now anything with an equal sign in the value will not get set
* Might want to have a way to escape semicolons?  Can you use a newline to split
the value?
