J. Ryan Stinnett 2c313e0c5e Add managed hybrid call widgets when supported
If your homeserver is configured with an experiment `widget_build_url`, this
will take over the functionality of the call buttons and turn them into a
general widget installer.

/*
* Manages a list of all the currently active calls.
*
* This handler dispatches when voip calls are added/updated/removed from this list:
* {
* action: 'call_state'
* room_id: <room ID of the call>
* }
*
* To know the state of the call, this handler exposes a getter to
* obtain the call for a room:
* var call = CallHandler.getCall(roomId)
* var state = call.call_state; // ringing|ringback|connected|ended|busy|stop_ringback|stop_ringing
*
* This handler listens for and handles the following actions:
* {
* action: 'place_call',
* type: 'voice|video',
* room_id: <room that the place call button was pressed in>
* }
*
* {
* action: 'incoming_call'
* call: MatrixCall
* }
*
* {
* action: 'hangup'
* room_id: <room that the hangup button was pressed in>
* }
*
* {
* action: 'answer'
* room_id: <room that the answer button was pressed in>
* }
