Bug 399501: Code formatter inserts line breaks after const qualifier

Update scanner to return correct tokens for JavaScript reserved
words. Currently, scanner treats keywords 'let' and 'const' in the
exact same way as 'var'. Additionally removed unused source level
comparisons to avoid problem in the future, hopefully.
