Stop LedDevice:write for disabled devices + Nanoleaf Fixes (#629)

* Handle Exceptions in main & Pythoninit

* Have SSDPDiscover generic again

* Have SSDPDiscover generic again

* Change Info- to Debug logs as technical service messages

* Nanoleaf - When switched on, ensure UDP mode

* Include SQL Database in Cross-Compile instructions

* Fix Clazy (QT code checker) and clang Warnings

* Stop LedDevice:write for disabled device

* Nanoleaf: Fix uint printfs

* NanoLeaf: Fix indents to tabs

* NanoLeaf - Add debug verbosity switches

* Device switchability support, FileDevice with timestamp support

* Nanoleaf Light Panels now support External Control V2

* Enhance LedDeviceFile by Timestamp + fix readyness

* Stop color stream, if LedDevice disabled

* Nanoleaf - remove switchability
