[Twisted-web] caching branch

[Andrea Arcangeli]

The tags.cached keeps working fine in the caching branch (which btw
applied cleanly on top of trunk).

What doesn't work is the rend.Page. I'm very curious to compare the
performance of the caching branch with my previous code that is
currently online already.

233

def CachedSerializer(original, context):

234

    cache = ICache(original.scope(context))

235

    cached = cache.get(original.key, original.lifetime)

Locals
original	<cached instance at 1455889540>
context	<WovenContext instance at 1455880172>
Globals
ICache	<MetaInterface nevow.inevow.ICache>
CachedSerializer	<function CachedSerializer at 0x56c63614>

I also suggest to apply this patch to the code or it doesn't even
startup.
