Disable the creation of tmp_* variables by TwigJs\Compiler\SetTempCompiler

This is part of schmittjoh/twig.js#12
Replace TempNameCompiler output with that of the regular NameCompiler

This is intended to deal with schmittjoh/twig.js#12, by finishing off the
process of disabling the tmp_variableName optimization which is not behaving
correctly under certain circumstances.
