Add «name» as optional parameter to export-action

[svenove]

Is your feature request related to a problem? Please describe.
When running the export-action, there is no option to give the export a name. This results in the export being named «-Camera-name- -start time- -end time-».

Describe the solution you'd like
The API-docs state that «name» is an optional parameter that can be included in the body of the request. It would be nice if that parameter could be added to the export-action.
