Fix for multiple throws + IP support

[bamo]

Hi,

So there was an issue where if multiple @throws are included in a @method block, only the last one is reflected in the generated docs. This is not a good system, because a method can certainly throw multiple different types of exceptions. This issue was both a parser and a template issue. In the parser, the throws digester just pointed to the return digester (which can only handle one instance). So, I made the throws an array rather than one value, and created a new digester for throws (based largely on the return one). In the templates, I simply made the throws a

with
• for each @throws (like @param).

  The second change is that you can create a server that is not simply localhost. You can specify yuidoc --server IP:PORT. This isn't required, though, and it retains the capability of the existing syntax (yuidoc --server PORT), in which case the IP defaults to localhost. So, this only adds a potentially useful capability while maintaining backwards compatibility.

  Thanks!
