Hledger.Utils.IO helpers have been updated and new ones have been
added (exitOnExceptions, exitWithError) to allow consistent display of
program errors whether compiled with GHC <9.10, GHC 9.10, or GHC >9.10.
The trailing newlines added by GHC 9.10 are gone,
and so is the "uncaught exception" output added by GHC 9.12.
A simple web-based user interface for the hledger accounting system,
providing a more modern UI than the command-line or terminal interfaces.
It can be used as a local single-user UI, or as a multi-user UI for
viewing/adding/editing on the web.
