Added rich string builder (a random access sequence, mutable buffer).
Fleshed out compat.StringBuilder some more to support this.

Rolled back buffered iterator to its simple "head" method form,
added advanced buffer iterator for multi-lookahead peak (call
buffered.advanced for advanced version)

Made string a random access seq. Deprecated utility fromString
methods for strings that no longer make sense (better alternatives in
RichString). Also, ensured that many seq operations return strings.
Changed deprecated accesses from XML library.

Made Stream a sub-class of Seq.Projection rather than a direct subclass
of Seq to support the lazy nature of Seq.

Deprecated type aliases in Predef, deprecated direct access to Integer
through Predef.

Added to to Range.
