/branches/htmlform

Convert initial DB connection error output to a sane page. Could arguably provide
space for this (and other) errors on all normal pages. (See #3).
This allows us to:

  • Remove editError sub in main.cgi
  • Remove printHeader sub in CommonWeb?.pm (see #15, #26)

Removed duplicate "exit if we get this far"
Tweak IPDB::finish so it doesn't spit a fatal error when called with a null database handle

  • Property svn:executable set to *
  • Property svn:keywords set to Date Rev Author
