Header ifdef guard should filter out illegal characters

[jgallagher]

The ifdef guard is currently defined as

"#ifndef cheddar_generated_{0}_h"

(likewise for the next line) where {0} is filled in with the header filename. For typical header filenames, this creates preprocessor tokens that look like cheddar_generated_filename.h_h, but . is not a legal preprocessor identifier character (clang under OS X gives a warning about "extra tokens following an identifier", pointing to the .).

Thanks for letting me know, that should be fixed now and I've done a v0.3.1 release for you. Could you check that it has worked then close this issue if it has please.

Yep, thanks!
