Description of changes
I went a couple of times through all functions, not much I found to optimize the Flash usage.
Overall this results in 1690 bytes less of Flash usage and 43 bytes less of RAM usage.
One important remark
I have deleted the usage of UniqueID for all AVR Boards. There was only less time where this was used. If a board was initialized in this timeframe, a new serial number will be generated with this change. I guess there are only verly less user who are affected, not to say no user is affected.
I vote to take now the chance to get rid of these serial numbers to not deal with them in the future.
If we should still keep them, I will add again the detection but without using the sprintf() function to take care of the huge flash saving.
@MobiFlight-Admin @neilenns @GioCC may I ask you to comment on this and to add ideas/changes for further reducing of Flash/RAM usage.
