Adding dynamic icons and Address

[neuvill]

This is a contribution that allows users to choose "Dynamic icons" as an icon and "Address" as a Device details (secondary text):

1- Dynamic icons:

In the device now you can choose Dynamic icon and this allows you to view the stat of the device (moving, idling and parked) directly in the device list or in the map and it changes dynamically depending on the state,

to allow this to work,we need to add a calculated attribute as follows:

Description: Dynamic status
Attribut: dynamicStatus
Expression:
motion ? 'moving' : (ignition ? 'idling' : 'parked')
Type: String

2 - Address:

Now the Address can be choose as device details (secondary text), just make sure that Traccar is connected to an unlimited reverse geocoding server and the conf file is correctly configured to always display the address.

PS
I also added the total number of devices in the search bar.

Wait, I thought dynamic icons mean you can upload your own icon. I'm not sure I understand the value of this change.

The idea is to have the stat of the device as you can see in the screenshot hereunder:

Allowing the users to add their own icons is a little bit tricky, it must be converted before storing it

[tananaev]

I don't think simply replacing existing icons make sense. Maybe the motion status can be on the right side of the list, next to ignition and other icons.

[tananaev]

Rotating icon on the map also doesn't make sense because we already have a direction indicator.

[tananaev]

In general this feature needs much more consideration and discussion before implementing.

Ok I see that, what do you suggest regarding the icons, and what about the address as Device details?

[tananaev]

I think address as device details is reasonable. We can do a separate PR just for that.

As for icon, I provided some suggestions above.
