Common tests for all clients to test against.

All files should be of the form:

{	"test1name":	{	"test1property1": ...,	"test1property2": ...,	...	},	"test2name":	{	"test2property1": ...,	"test2property2": ...,	...	} } 

Arrays are allowed, but don't use them for sets of properties - only use them for data that is clearly a continuous contiguous sequence of values.
