Ability to highlight non-standard account names

[hrj]

Sometimes, due to typos or WIP entries, there are accounts that are neither in Balance sheet nor in P & L statements.

These need to be highlighted.

Two ideas:

1. Highlight them in the All report. Could be achieved by adding a configuration in the report.
2. Add a top-level configuration to recognize standard Account names. A summary of all non-standard account names can then be presented as a warning message.
