Think about to fix the issues found by adapter checker

[ioBrokerChecker]

I am an automatic service that looks for possible errors in ioBroker and creates an issue for it. The link below leads directly to the test:

https://adapter-check.iobroker.in/?q=https://raw.githubusercontent.com/volkerrichert/ioBroker.oppoplayer

• [x] [E801] No repository about text found. Please go to "https://github.com/volkerrichert/ioBroker.oppoplayer", press the first "Edit" button you will find on the page and add the description.
• [x] [E605] No actual year found in copyright. Please add "Copyright (c) 2019 Volker Richert volker@richert.nrw" at the end of README.md
• [x] [E701] No actual year found in LICENSE. Please add "Copyright (c) 2019 Volker Richert volker@richert.nrw" at the start of LICENSE

I have also found warnings that may be fixed if possible.

• [x] [W113] Adapter should support compact mode

Thanks, your automatic adapter checker.

P.S.: There is a community in Github, which supports the maintenance and further development of adapters. There you will find many experienced developers who are always ready to assist anyone. New developers are always welcome there. For more informations visit: https://github.com/iobroker-community-adapters/info
