Server message should not log with FATAL marker.

Will instead have the SERVERMESSAGE marker again.
Refactored database API (Sorry :( )

It's now a tad more flexible and works better in real SQL type databases.
Instead of strng[], object[], most API methods will now expect a Map<String,Object>
that rpresents the column-name/value mapping.
Also DataAccess now has a mandatory id field which all dataaccess tpes will have.

On the way there, there were also some smaller bug fixes.
For instance, the reserve-list now doesn't try to look in the whitelist table.
