Made mail configurable via a YAML file. A dummy one is included in this commit. Also made a launch file.
Times are not represented as uint32-encoded unix time stamps since epoch, just as ROS does by default. The timezone Maluuba sends is not clear, so converting to the local timezone is not yet correct. For me, converting to GMT+2 somehow works, but EST or CEST does not. WIP
Set the original timezone to Montreal, not the conversion is 5 minutes off somehow
Also parsing TimeRanges to integers now. Also made things a bit cleaner, but some cleaning up of imports is still required.
