use GWTTestSuite for GWTTestCases

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run ant.
2. Have many hidden hosted modes created.
3. Have the build take 3 minutes, 21 seconds on new MacBook Pro.

What is the expected output? What do you see instead?
A common technique is to put all GWTTestCases into a single (or a couple large) 
GWTTestSuites 
so only one hidden hosted mode needs to be launched to run a number of 
GWTTestCases.

What version of the product are you using? On what operating system?
r74 on Mac OS X.

Please provide any additional information below.
I'll try to see if I can provide a patch, but I'll need to set up Eclipse to 
follow the style rules so I 
can contribute.

I can confirm this - running the all tests together in IntelliJ takes less than 
30s
total.  I'll look into it.
