Usage Advice: Describe how an execution can have its own configuration

[lonniev]

It might help to state in the Usages that one can set up their pom to perform multiple executions of the plugin for the same goal and phase (just as can be done for almost every maven plugin).

The 'replacer' will use the configuration element within the execution element along with the configuration element after the executions element to form the proper configuration for a specific execution from both the particular configuration and the shared, common, general configuration.

For example, file and outputFile elements might be found within an execution while replacements or toggles such as ignoreMissingFiles could be stated once in the outer shared configuration.
