    Add gitref macro to reference a git hash
    
    With this extension a git hash can be easily referenced.
    
    The porters handbook versions chapter uses this extension
    as an example in the FreeBSD 14.0 version table.
    
    An example of use
    
    gitref:hash[repository="src|doc|ports",length=hash-longitude]
    
    The repository should be src, doc or ports.
    And if no length it's specified the macro will use 12 characters
    of the specified hash.
