Wip/proxy support
First cut at atmos support in 0.13
Attempting to add atmos listener hooks.
We can add the hooks by determining if atmos is configured for the project,
but none of the listeners are firing when trying to call atmos:run.
Fix up atmos:run for sbt 0.13 test to pass

 * need to makeAppendSettings before doing reloadWithAppended
 * don't kill the test when atmosStarted arrives
 * send the correct request in the test
 * add toSpecific code that works for atmos:run to RunResponse
 * remove debugging println
factor out common code for run and atmos:run
add 0.13 support for atmos:run-main
include props jar in 0.13 launcher files
name integration test ActorSystem IntegrationTest instead of ManualTest
Test 'test' task for 0.13 also and fix it

makeAppendSettings was missing.
Lengthen timeouts to encourage integration tests to pass
