Flipped the include guard and the pragma, and don't use the pragma for early versions of gcc (< 3.4)

Fixed flow folding, and made the separation slightly cleaner (but the whole scanscalar thing could use a major refactoring)

Moved the three scalar token scanning functions back to scantoken.cpp, so scanscalar.cpp now only has the main scalar scanning function.
Renamed ScanScalarInfo to ScanScalarParams.

Renamed the valid/possible tokens to a single variable status with enums valid, invalid, and unverified.

Moved the input stream, together with line/column info, into its own class, which allowed some other stuff just to pass the stream, and not have to be a member of Scanner.
