Compilation issues

A few typos and missing functions resulting in compilation errors in Arduino IDE

Please check the above commit - this at least gets it compiling. If you intended to eventually remove the statusLight function, no problem. I did add it back in to make it compile.

I see now what was happening with statusLight actually. It looks like you've moved the function to InterlockFunctions.ino but there are still some things in AccessControl.ino that still rely on that function when DOOR is defined.

If you accept this pull request, I can fix that next go.

I also intend to add support for RC522 RFID module
