dartdoc: add libraries by their real filename

This came up with dartdoc.dart (bleeding_edge, r 5635)

In dartdoc the docIndex method creates a listing of the processed libraries (stored in _sortedLibraries). Currently the 'uri' entry is displayed twice.

The problem is in lang/world.dart > getOrAddLibrary(filename), where processing of filenames 'dart:uri' and '../../lib/uri/uri.dart' leads to 2 entries in the libraries array.

Using the attached patch i first sort of normalize the filename and then process the file.
