fixes & improvements

- refactored main.go to do everything which requires root *first*,
  before dropping privs. this includes binding to finger and gopher
  ports.
- added gopher support!
- fixed CGI handling
- new cgi-bin/private directory handling in gemini which requires
  specific TLS client certs (can't do this in gopher, no TLS)
- sliderule version bump brings in lots of fixes on the sliderule side
