Subject [15/24] incubator-brooklyn git commit: WIP - change semantics of parameter addition
Date Thu, 14 Jan 2016 23:54:29 GMT
WIP - change semantics of parameter addition

api EntitySpec.parameters(...)  should *add* parameters, like the other methods;
since parameters have just been introduced it is fine to do this

also comments and tidy of other merges
