Reconciliation parsers don't support all supported database names

Due to the inclusion of the database name in the function name of the database parser (see https://github.com/ledgersmb/LedgerSMB/blob/master/lib/LedgerSMB/Reconciliation/CSV.pm#L73), company names can't include any symbols which aren't supported in Perl symbols (e.g. !@).

We need a better design to hook parser code to accounts.
