Allows you to create *_custom.properties files for overlaying stock strings with <messagecatalog>.

So for example, a recent commit changed how circ modifiers are displayed in the staff client, with

common.properties:
staff.circ_modifier.display=%1$s : %2$s : %3$s

You could do this for the original rendering:

common_custom.properties:
staff.circ_modifier.display=%1$s

The custom file need only contain the properties that you wish to change.

The xul <messagecatalog id="commonStrings" src="/xul/server/locale/<!--#echo var='locale'-->/common.properties" /> will attempt to parse both common.properties and common_custom.properties
