[Seaside] 2.5b2

[Avi Bryant]

Hi folks,

Just released Seaside 2.5b2.  The changes from b1, mostly thanks to  
Adrian Lienhard and Michel Bany, are:

- added #orderedList: and #orderedList:do: to AbstractHtmlBuilder
- fixed Application>>name to allow an empty basePath
- fixed #findStyles to include the request in the context
- fixed #valueInputOfType:value:callback: to use the raw string instead  
of throwing an error when it is expecting a number in the callback but  
doesn't find one
- added a 'Cache-Control: No-cache' header to rendered pages by default

I've also been experimenting some with Javascript's XMLHttpRequest  
support, and have included a preview of this work.  You can read more  
in this blog post, and see an example in WALiveRequestTest:

Like the Canvas work, this is *not* a supported part of Seaside 2.5,  
but since it's independent of the rest of the code I don't mind keeping  
the previews in the release.
