- Correctly display safety status
- Add override status

prevent magic lib failure from crashing http server

Add support for keeping last known values in trace_proxy
(Can be used for dt position while console/controller is offline)
Reduce sun and moon time offset to 2 seconds
Add UTC time of controller trace to gui
Fix some padding in dt_ui javascript

Also added stdin mode to trace_dump usage text.

Add TRACK setpoint to http server.

Small pwm fix
(added t_off)
vesp fixes, communication seems to be buggy

Fix some small command handling stuff.

Add 't_off' parameter to am335 pwm block.
t_off will be the minimum time the bridge is switched low per pwm period.
(To allow boost C to recharge)

Can be used to quickly send float setpoints for testing.

(This might cause order dependent bugs...)

Fix vesp controller block.

Can be used to calculate a voltage limit based on the current voltage and
current and a current limit.

Add script to enable pwm on beaglebone

Determines current limit based on the i2t algorithm.

With this block motor state can be derived from voltage and speed.

Tested with beckhoff blocks connected.
(Still only one ethercat bus, multiple busses remains untested.)
