Added a "reload" command, for use at the REPL

Created a new function, session_t::reread_journal_files, which throws
away all previous state data and reads in the same files again.  This is
needed to allow Emacs to communicate with Ledger via the REPL, so that
it tell Ledger when it has made changes to the user's data file.
