WIP: Create telemetry scheduler.
GUI works, as does saving and loading files.
Currently does not change settings because there is no method for universal
settings changes.
Added copy/paste functionality.
Added frozen table row, for displaying telemetry rate required.
Updated TelemetryScheduler dependencies.
Reordered telemetryschedulergadgetwidget header file.
Added support for setting metadata.
Removed commented code.
