Android "Thin client" for AKM program

Used by 'KLine_Ethernet' and 'CAN_Ethernet' AKM Data Sources (Connection type: "WEB Server").

Supports whole range of ABIT LNK adapters as well as Ixxat CANBlue and ELM327 bluetooth adapters.
Note on ELM327: only ELM327 v2.2 are tested and supported.

Android client was tested on Android 7, Android 10, Android 11 and Android 12 versions. Client can possibly be used on the other versions (minimal required are listed below) however not tested.
Note: on WEB Server this client always uses single account 'ABIT.client' (dongle id: 915174728). So at any given moment only one such client can be active (even in case two clients are run on different phones).
