* Add event loop to the core * Add block_till_done to HA core object * Fix some tests * Linting core * Fix statemachine tests * Core test fixes * fix block_till_done to wait for loop and queue to empty * fix test_core for passing, and correct start/stop/block_till_done * Fix remote tests * Fix tests: block_till_done * Fix linting * Fix more tests * Fix final linting * Fix remote test * remove unnecessary import * reduce sleep to avoid slowing down the tests excessively * fix remaining tests to wait for non-threadsafe operations * Add async_ doc strings for event loop / coroutine info * Fix command line test to block for the right timeout * Fix py3.4.2 loop var access * Fix SERVICE_CALL_LIMIT being in effect for other tests * Fix lint errors * Fix lint error with proper placement * Fix slave start to not start a timer * Add asyncio compatible listeners. * Increase min Python version to 3.4.2 * Move async backports to util * Add backported async tests * Fix linting * Simplify Python version check * Fix lint * Remove unneeded try/except and queue listener appproriately. * Fix tuple vs. list unorderable error on version compare. * Fix version tests
