- Fixes critical mistake in boot.php regarding set_include_path - Fixes minor mistake in text.php regarding strpos order of arguments Note: This change significantly increases Composer running time because Text_Highlither is a PEAR package. I'm already planning to replace it with scrivo/highlight.php.
