Feature remote control highlight

[singhsanket143]

The pull request is implementation for the feature listed in issue #16863. Implementation of Remote control of a projected instance from another device has been implemented in this pull request. The package named yuukan:streamy has been used to establish real-time communication between different devices. Whenever the admin checks the highlight instance checkbox all the other devices will show the effect of emphasizing and de-emphasizing on them.

1. From the admin end.
   

2. From the other user end

@singhsanket143 the whole implementation is on the client side and people with skills will be able to fake it, can you make sure it's not possible?

[peter-hank]

A few more changes.

@singhsanket143

Not all of the requested changes are done. Can you go through this again?

[peter-hank]

It's still overcomplicated.

The logic should be:

• click on the highlight button
• check on the server part if the user is admin
• if so, broadcast and apply on the client side, if not don't do anything

Can you try to simplify it?

@peter-hank I have tried to simplify the code. Please review it.

@singhsanket143 can you make the Highlight the question label clickable?

@singhsanket143 can you make the Highlight the question label clickable?

@peter-hank So on clicking checkbox as well as on label the highlight action should occur?
