Debian package: Mark asm3.conf as configuration file

[mathieumd]

Debian package should be constructed in order to state that /etc/asm3.conf (and /etc/apache2/sites-available/asm3.conf, I think) are configuration files.

That way they would not be overwritten when package is upgraded.

Because I lost my conf file on upgrading v48 to v49 :-/

It's been a while since I wrote the script that creates the deb package. I could have sworn that dpkg automatically treated anything that goes into /etc as a config file, but it looks like I was wrong. I've fixed our script to correctly create DEBIAN/conffiles in future, thanks for the heads up.
