Leaving out type names during compilation

[auxym]

Methods and class inheritance need runtime type information in order to 
function. Maybe don't use these nim features if you don't want types in the 
compiled code. Or use some sort of automated C obfuscator before calling the C 
compiler (you could write some sort of shim program that obfuscates then 
forwards to gcc and tell nim to use that as a compiler by setting 
`gcc.exe:my-obfuscator-shim`).
