upgrade twisted to 8.0.1

[yqiang]

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 (reset() doesn't restore anything in all_cmdline or all_notebook #1042, Cython working directory command line option patch #3030)
• LoopingCall now allows you to specify the reactor to use to schedule new
  calls, allowing much better testing techniques (Notebook tweaks #2633, Unable to create certain multivariate polynomial rings since libsingular is invoked instead of generic code #2634)
• twisted.python.log now contains a Twisted log observer which can forward
  messages to the Python logging system (notebook -- for person users admin is usually the only user -- in such cases fill it in as the default #1351)
• Log files now include seconds in the timestamps (support for rook monoid and planar rook monoid (as well as their diagram/partition algebras) and a few other misc. fixes #867)
• PB now supports anonymous login (Interface with remote programs allowing for as many hops as needed #439, Add support for bracelets, necklaces, and Lyndon words, of a fixed length #2312)
• twisted.spread.jelly now supports decimal objects (gcc 4.3: fix rubiks.spkg build #2920)
• twisted.spread.jelly now supports all forms of sets (twist.py -- doctest failures in sage-3.0.alpha6 on some test machines #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,
