- use dba::is_result() everywhere (where I found the old, bad way)
- converted some spaces -> tabs for code
- converted some CRLF -> LF as mixures of both is not good

Only define functions if they have not been defined before, e.g. in themes. This makes it possible to override parts of a module and still use the other functions.
