[20160628221152] Parameter Consolidation

This release consolidates parameters in the CloudFormation stacks for applications. Because CloudFormation stacks are limited to a maximum of 60 parameters this
change allows more process types to be defined for an application.

Previously each process type in your application used three parameters to define scale:

"WebCount": "3",
"WebCpu": "0",
"WebMemory": "512"

After this change, these parameters have been consolidated:

"WebFormation": "3,0,512"

You can now run up to 40 unique process types per application.

Thanks to @jamiequint for feedback and for running an enormous application on Convox :slight_smile:
