On some systems, StopClient et al can take a long time to execute.
Instead run these on a separate thread to avoid blocking the GUI.
Also add option to get IP from DS (default on).
Instead of "/SmartDashboard/name" they now default to "name (SmartDashboard)".
This allows for smaller windows while preserving the name without requiring
user customization.
This modifies the mecanum drive, differential drive, speed controller,
and PID controller widgets to only be writeable when .controllable is
set to true.
A few virtual functions are called by constructors or destructors, which is
dangerous in C++ (as an overridden virtual impl won't be called, only the
one in the current class). Fix by either marking the function final or
not calling at all (if possible).
This makes code easier to read and more consistent between C++ and Java.
Also update clang-format settings to always add a line break (even if no braces are used).
This reuses many pieces of the current simulation GUI. The common pieces have
been refactored into the libglass library.
The libglass library is designed to be usable for other standalone data
visualization applications (e.g. viewing data logs).
The name "glass" comes from "glass cockpit", as the application features
several multi-function displays that can be adjusted to display robot
information as needed.
