Subject: [PATCH] [dwpost] Cleanups: - used type-hint `App` and no
 call-by-reference - converted spaces -> tab for indenting - DBA::isResult()
 used instead of empty/count/... - added curly braces and spaces for better
 readability - opening curly brace after function/method/class belongs into
 new line
