Work around the problem of not being able to just put index.html into Qi, and

have the brower interpret it as HTML when browsing the repository through the
Web interface: generate a test.html by default, with local paths, and generate
the real index.html, with remote URLs, when uploading.

- web/style.sh: only set BASE if not set already in the environment
- web/Makefile: added test.html target and made it the default
- web/index.sh: ben-dispbase-back-100um is running now, switch to "in progress"
- web/index.sh: switched 100 um ben-bottom-nobat scan from "under
  consideration" to "planned". In fact, it's the next in line.
