Continued a bit:

- removed/fixed whitespaces and mixture of spaces/tabs (some)
- added new-line character at end of files (POSIX-compilant)
- reverted some code which I had messed up (compared to upstream/develop)
- removed duplicate dba::update() invocation in src/Protocol/DFRN.php
- also removed no longer valid TODO
