Allow multiple report suites per application

[#1]

We want to send app data to multiple report suites - an app specific one and a global rollup which also contains our website traffic data. Currently when we modify the mappings to evars and props processing rules are created in the app report suite but not the global report suite. This is causing a large admin overhead. It would be ideal if you could specify a secondary report suite for an app so that the processing rules are consistent across all report suites
