Fix output buffering warning

Thanks to a fix by @rkaiser0324, even when on the lowest output buffering level (i.e. no buffer has been created), this library won't throw an error.

Use system temp path

Before, the temp path was hardcoded to /tmp/. Now it uses the actual system's temp path, to make the library more compatible with non-*nix systems.
