[dw-free] Allow local package installation

[mark]

[commit: http://hg.dwscoalition.org/dw-free/rev/c73da7d459cd]

Allow local package installation

This is mostly for my development environment. It allows the usage of cpanm
(http://cpanmin.us/) to install packages locally as the dw user. These
packages are installed in $LJHOME/extlib/ by convention.

I'm testing this out and seeing if it's a good plan for production or not.
It might be interesting because then we can just push the extlib directory
out, possibly? I'll experiment with it.

Patch by mark.
