[with spkg, positive review] upgrade twisted to 8.0.1

[yi]

A major new version of twisted has been released and I strongly recommend that we upgrade to it for sage-3.0. There are a ton of new features and many bug fixes. Some specifics that are relevant to dsage are:

• The reactor now has a blockingCallFromThread method for non-reactor threads to use to wait for a reactor-scheduled call to return a result (#1042, #3030)
• LoopingCall? now allows you to specify the reactor to use to schedule new calls, allowing much better testing techniques (#2633, #2634)
• twisted.python.log now contains a Twisted log observer which can forward messages to the Python logging system (#1351)
• Log files now include seconds in the timestamps (#867)
• PB now supports anonymous login (#439, #2312)
• twisted.spread.jelly now supports decimal objects (#2920)
• twisted.spread.jelly now supports all forms of sets (#2958)

Also, this release is easy_install'able. I don't know if we ever use easy_install to install packages or what the thought on it is.

I guess the "Summary" is supposed to say SPGK.

mhansen did play with this and did give it a positive review. It builds and installs fine for me. I added a mercurial repo and some other small bits.

Cheers,
