Updated werc: featuring SMAK and hgwerc

The 4l77.com site has suffered a severe clean-up. Werc has been updated to its last version and customizations are less invasive now; every site is stored in a different hg repository.

My personal site (http://yiyus.info) has been updated too, and includes a new werc app: SMAK, a (very simple) image gallery. Both sites include custom rc functions and template files. I also tried to improve my customized hgwebdir system so it can be useful to more people, it is also available as a repository.
