Title: Added support to a vrpn tracker device url that includes specifying the ...

...sensor id of the desired tracker

(there may be multiple sensors on at the same address). The default is to gracefully find and use the lowest
active sensor. Specify vrpn_tracker as: @[:][?sensorid-(any|)]
e.g.,: Tracker0@tracking.cluster&sensorid-1

Note: loader.* EQTOKEN_STRING does not permit some symbols (e.g., ? or =), so we use - for = instead
