Linux installation: search path for dmd.conf

[Norbert Nemec]

Hi there,

playing with my DMD installation, I notice that the
D-installation-web-page gives the instruction to place dmd.conf in
/etc/dmd.conf

This is a real problem if you are not administrator yourself. The
compiler should fist look for a file in the home directory, (e.g.
~/.dmd.conf) before falling back to the system-wide location /etc/dmd.conf.

In case a solution like this is already in place, it should be
documented in the installation page.

Greetings,
