Make mtedit Python 3 compatible

Due to the way relative imports work in Python 3, mtedit/main.py has to
be moved outside of the mtedit package, as when run using its hashbang
line it is package `__main__`, and therefore cannot use relative
imports.

The other manual changes are:

* to properly distinguish between strings and binary data in
  mtlib/util.py, mtlib/log.py, and mtedit/server.py;
* to switch between methods for getting headers in mtedit/server.py; and
* updating some `import` statements (as well as removing unused ones).

The rest of the changes were done using `futurize`:

    $ futurize --stage1 --all-imports --write --nobackups mtedit/**/*.py

Two features remain broken:

* retrieving logs over SSH fails to retrieve
  /var/log/xorg/cmt_input_events.dat, but that was broken already; and
* editing logs by adding the `-o` switch and clicking the shrink button
  in the Web UI fails to import `MTReplay`, presumably because I haven't
  updated that module yet.

TEST=run `mtedit` with the path of a downloaded ZIP file, choose a log
     to view, and check that you can view the data properly in the
     browser.
BUG=none
