fs.copyfile to replace configure_file(copy : true)

A new method has been added to the fs module, copyfile. This method replaces configure_file(copy : true), but only copies files. Unlike configure_file() it runs at build time, and the output name is optional defaulting to the filename without paths of the input if unset:

fs.copyfile('src/file.txt')

Will create a file in the current build directory called file.txt

fs.copyfile('file.txt', 'outfile.txt')

Will create a copy renamed to outfile.txt
