Combined the myriad ScannerExceptions and ParserExceptions to a single ParserException class that has a message and a line/column position in the file where the error occurred.

Added parsing of anchors, aliases, and tags (still no semantics yet).
Fixed a silly bug in the simple key pushing (queues are FIFO!).

Instead of deriving different tokens from a base Token class, we now use an enumerated TOKEN_TYPE to distinguish types. This is so we don't have to cast all the time when parsing the resulting token stream.
Also, removed start/end stream tokens.

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.

There's a bug (and question): should we test simple keys' validity BEFORE stuff or AFTER stuff?

Wrote a simplified regular expression parser to make life easier (it only does single matches; i.e., no one-or-more matches, etc.).
Fixed some of the whitespace/line break matching.

The plain scalar scanner is almost done (and it scans a simple list correctly).
Also messed around with multiple character peeking on the input, and got something working.

Continued working on scanner.
We're now using exceptions for errors, and scanning/pushing tokens is exception-safe (using a set of "limbo tokens").
