- Escaped backslashes before insert into DB. This fixes display errors

for e.g. Windows filespaces. This is also only a ugly workaround. A
  DB dependend escape of SQL statments via ADODBs 'qstr()' would be much
  better, but needs code refactoring.
- Allow to save empty config field values. Needed to enable/disable file
  logging.
- Fallback logging to STDOUT if given logfile not accessible.
