Merge remote-tracking branch 'origin/topic/bernhard/sqlite'

* origin/topic/bernhard/sqlite:
  fix a few small rough edges (mostly comments that do no longer apply)
  fix bug in input-manager regarding enums that a writer reads without 0-terminating the string
  actually make sqlite work again (tests passed because the writer was not actually defined because of the define.)
  add sqlite distribution.
  fix warnings, update baselines, handle rotation
  add sqlite tests and fix small vector/set escaping bugs
  fix small bug with vectors and sets.
  make work with newer AsciiFormatter.
  start adding a different text for empty records for the sqlite writer.
  no, you will never guess from where I copied this file...
  make sqlite support more or less work for logging and input
  make sqlite-writer more stable.
  make it compile with new version of AsciiInputOutput
  and adapt to AsciiInputOutput - seems to work...
  make it compile
  add SQLite reader.
  ...adapt to new api...
  now the writer supports tables and vectors.
  basic sqlite writer seems to work.
