Add "Click to Allow Adobe Flash Player" to Clappr.FlasHLS

[MediaJunkie1]

Browser: Chrome Version 69.0.3497.100 (Official Build) (64-bit)

OS: Windows 10

Clappr Version: Latest

Steps to reproduce:

1. Use Clappr.FlasHLS plugin to force Clappr Flash player without fallback.

Did you try to reproduce this issue at http://cdn.clappr.io/ : Yes

When using Clappr.FlasHLS plugin with no html5 fallback, users must manually enable flash for the player to load. I propose adding code to the swf file which will display a prompt to "Click to Allow Adobe Flash Player" if the user does not currently have flash enabled for the website. This will make allowing flash much easier for users.
Example of 'Click To Allow' Button on POGO Games

Also, recently Google Chrome has updated and now forces users to enable flash for each domain for every new browser session. This makes it more important to have a fast, easy way to enable flash video when needed.

Thanks for all your work team. :)
