As older PHP version can cause multiple problems, and we still use lots of requires that can generate PARSE_ERROR on such version, we chose to add this very low-level control. Therefore user will get a clear error message, and oldest PHP version will be blocked in the whole application.
- bootstrap.inc.php is now included by approot.inc.php
- remove all unescessaries includes of bootstrap.inc.php
- in bootstrap.inc.php autoload can be bypassed using a feature flag because "why not"
