[Pdxpw-staff] install instructions for Sublime Text 2

[Kevin Turner]

Installing on Windows is straightforward enough:

I then started on the "indent uses spaces" docs, as the Boston Python
Workshop has.  I realized it's not Windows-specific, so I put it in
another document:

and it turns out that ST2 is not actually any easier to configure than
emacs is.  :-(

If anyone is hacking at project night instead of mentoring, a good
project might be to write a script for Sublime that:

* sets syntax-specific preferences for Python to 4-space indent
* installs Package Control
* installs a linter that is not too crazy (see comments in the google
doc's margin notes)
* gets SublimeCodeIntel to work

and I still think people should have ipython or bpython but even ipython
on windows is not exactly a one-click process.
