Add more formats to `git-du`.

This adds support for object, meta, and log views.
- object   view disk usage of each object group.
- meta     view disk usage inside the '.git' directory.
- log      view disk usage for each commit (needs work).
Add `sec-check`.

This performs some common security checks, including:
- empty password checks
- suid/sgid file hunting
- 777 permission hunting
- incorrect permission checking
- mount flag checks
Remove debug prints from `viname`.
Add directory support to `viname`.
Add log-like support to `git-wc`.

This shows word counts with the log.
Add scripts to Makefile.

- vimv
- sec-check
Add 'install-quiet' target to Makefile.

This installs the scripts without making any noise. This also adds a fix
to keep 'diff' in the 'check' target from printing.
