Saving a file does not always completely overwrite the old file #117

The xtt_save_to_file function does not use the O_TRUNC flag when opening a file. Consequently, if the new contents are shorter than the old contents, the tail of the old contents remains at the end of the file.

Yep, good catch. Sorry about that.
