Guessing package version for DLA template

[Bálint Réczey <balint@balintreczey.hu>]

Hi,

Since I made mistakes in setting the package version in DLA texts (and
I'm not alone ;-)) I came up with the attached patch which makes
gen-DLA and guess the proper one.

If both teams like it I'll push it to the repo.

Cheers,
Balint
