- support for general html tags
- better names for a few identifiers

godoc.go:
- emit links from exported names to source code
  (actual placement needs fine-tuning)

types were supposed to be identical but only needed to be
compatible.  This gets rid of the Type.literal method.  I
renamed the Type.rep method to Type.lit because I believe it
corresponds to the term "literal" as used in the spec.

- more orthogonal functionality of filter functions for better re-use

go/doc/doc.go:
- simplified interface
- collect filenames of packages so that they can be shown

godoc:
- removed TODO, show list of package (linked) files used to create documentation

Return checking is now done as a general flow check at the end
of function compilation, since break and goto complicated the
way I was doing return checking before.  Goto-over-declaration
checking is also done as a final flow check.

Temporary variables used for effect extraction are now
actually temporary.  Otherwise "op=", "++", and "--" appear as
declarations that cannot be jumped over.

- Changed filter function for parser.ParsePackage to
  take an *os.Dir instead of a filename for more
  powerful filters

- Removed TODO in ast.PackageInterface: Now collect
  package comments from all package files

- Cleanups in godoc: Use the new ParsePackage and
  PackageInterface functions; as a result computing
  package information is much simpler now.
