Switch back to Gibiansky style.

There was a bug in HIndent, the pretty-printer I use for the indentation. The
Gibiansky HIndent style was generating an invalid AST, so I temporarily switched
to another style. The bug is now fixed, so I can go back to the Gibiansky style.

Add journalNew, fix journalList functions.

Previously, journalList would try to read the journals from the current working
directory, rather than the application user data directory. I fixed that, and
added the capability to create new journals.
