Don't automatically add extension to file names

[apteryxxyz]

There are a handful of runtimes that automatically always add file extensions to file names. For example, C++.
This is annoying as - for example - C++ header files test.h will be appended with .cpp, which is undesirable.
I request adding an option to specific you don't want extensions automatically added (rather than changing the existing default as to not break any existing code).

Hey, i too am not sure why the files are being renamed but if you are self hosting then updating the compile script which is responsible for adding the extension to the files should help you

So you can prevent renaming in case of cpp my commenting this line
