Bug#778962: naturaldocs: please make the output reproducible

[Chris Lamb]

Source: naturaldocs
Version: 1.51-1
Severity: wishlist

Hi,

While working on the "reproducible builds" effort [1], we have noticed
that naturaldocs is not generating deterministic searchdata.js files.

The attached patch removes this randomness. Once applied, packages using
naturaldocs can be built in our reproducible toolchain.
