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/ioBroker/ioBroker.history

• [E151] common.connectionType type has an invalid type none
• [E506] "admin/jsonCustom.json" not found, but custom support is declared
• [E605] No actual year found in copyright. Please add "Copyright (c) 2014-2022 hobbyquaker hq@ccu.io" at the end of README.md
• [E701] No actual year found in LICENSE. Please add "Copyright (c) 2014-2022 hobbyquaker hq@ccu.io" at the start of LICENSE

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

• [W801] .npmignore not found

Thanks,
your automatic adapter checker.
