View source for Check code

This function make able to create a vendor code with correct checksums  after any change.

There are two checksums, CC_BASE and CC_EXT, that define data integrity of the code body. In the tabs CODE DETAIL and TABLE the checksum bytes have addresses 0x3F and 0x5F. 

The software automatically recalculates checksums when any byte changed. Remove a flag in menu '''Edit -> Autoset Checksum''' to disable this function or set up to enable.
