/**
* A replacement error handler with improved debugging features
* - Backtraces including function parameters will be printed using TextMate URLs when running on localhost
* - Only the IMP_FATAL_ERROR_MESSAGE will be displayed if IMP_DEBUG is not defined and true
* - Most errors (all if IMP_DEBUG is true, < E_STRICT otherwise) are fatal to avoid continuing in abnormal situations
* - Errors will always be recorded using error_log()
* - MySQL's error will be printed if non-empty
* - E_STRICT errors in system paths will be ignored to avoid PEAR/PHP5 compatibility issues
