public function StoragePhp::export in Configuration Management 7.2

Adapted from CTools ctools_var_export().

This is a replacement for var_export(), allowing us to more nicely format exports. It will recurse down into arrays and will try to properly export bools when it can, though PHP has a hard time with this since they often end up as strings or ints.
