ROS1 joy cleanups

It was done in a very complicated way before, but the idea is
actually simple; on a button press, toggle the value, on a button
release, do nothing.  This changes it to implement that logic.

Minor: moved default to right indent level

Maint/ci add melodic build

Since this is available on the ROS build farm, prerelease testing
is essentially done every time a new release is created and merged
in ros/rosdistro, prior to being merged to production. If something
fails there, we'll know it and be able to fix it before the release
merge happens. This cuts the build time dramatically and, IMO, isn't
necessary.

add joy_remap and its sample

return instead of shutdown

Cleaning up Python indentation.

Check if wiimote is still connected.

Add Basic Force Feedback Support

Modernize Python 2 code to get ready for Python 3

Put brackets around ROS_* macros.

In some circumstances they may be defined to empty, so we need
to have brackets to ensure that they are syntactically valid.
