Clean up binary templates

[exectails]

The binary templates are a little chaotic atm, and it's only gonna get worse. We'll have to clean up in there some time.

• Move every group of related structures from common.bt into a dedicated file in a sub folder "inc".
• Introduce a general naming scheme for variables and structs.

This will make maintaining them and keeping track of the history much easier.

The structures have been moved to dedicated files for cleaner management, but the naming scheme is still all over the place.
