Matitaweb:
Improved support for notations enriched with hyperlinks.
This revision introduces a "ref" keyword which can be used in the lefthand side
of notation statements. "ref" can only be used to decorate literals (i.e.
symbols, numbers, or keywords). The syntax is as follows:
LITERAL ::= SIMPLE_LITERAL
| ref CSYMBOL SIMPLE_LITERAL
For example, the notation
ref 'cons [ list0 x sep ; ref 'nil ]
used as the compact notation for lists specifies that the `[' symbol will be
enriched with the interpretation of 'cons nodes of the AST, and the `]' symbol
with the interpretation of 'nil nodes of the AST.

Matitaweb: Fixes a bug in the extensible parser which caused Matita to crash
when parsing a notation using keywords (rather than symbols). The semantic
action associated to the notation was expecting the parser to decorate the
keyword token with its location: this was not happening, causing a runtime
type exception.
