- added new backup tables

- and some cleanup

- changed test runner protocol

- added hardMemoryLimitInKb, hardDiskSpaceLimitInKb as glbal config settings (removed from individual plangs)

- moved stats to separate dir
- changed included to work with dirs

- changed environmentVars to use \r\n as delimiter (because phpMyAdmin uses this)

- added some catches for main test executing calls

- included latest db dumps

- updated readme

- changed the protocol specs so that the program exit code and the expected program exit code are separate items (to display test content)
  - the program exit code is always the first item (if present)
  - the expected exit code is the second or first item (second only if we have a real program exit code as first item)

- updated docs
- added version string

- removed ipaccess file var

  - not removed dirs are bad but might help to trace back errors...
  - there were some timing issues when we ran multiple tests with one requests and the dir changed...

- made firejail compatible

- if the compilation fails and we have > 1 tests we copy the failed compile outout into every test result

- added option to get config from a sql db
- removed ip access control
- added stats.php to get test server configuration

- moved parameters max lines to read, max err lines to read, max lines to write to the test server (from test runner)
- updated readme

- added a check if the given regex line is really a regex (was missing for no and && no or connected -> normal regex)

  - no longer escapes are required because no longer json

- also the cleanup is now done if regex encountered an error
  - also done if we cannot create the temp dir

- warning output added
  - we get an error from time to time because we canno delete a temp dir...
