ShephardProperties does not always load properties from the correct path

[doinkythederp]

ShephardProperties is passed relative paths when loading properties, which are read relative to the current working directory. This is often the Tomcat install (System.getProperty("catalina.home")), but this is not always true (e.g. when running Tomcat manually or when using the Homebrew service). Thus, properties will sometimes fail to load.

#505 proved to be a breaking change. issues need to be resolved for this to be considered complete

We could not load Properties files on an Ubuntu 18.04 machine, causing Wildbook to fail to start and throw messages such as:
