Add -q0 option to nc in docs

With some versions of nc, the connection is kept open after all data is sent. Using -q0 parameter will make nc quit immediatly after EOF on stdin.

Debian has two debian packages for nc: netcat-traditional and netcat-openbsd. The former hangs after EOF on stdin, whereas the latter quits. I assume the expected behavior is to quit nc after sending the metric data.

Docs/tools: add pipe-to-graphite

We wrote [pipe-to-graphite](https://github.com/iFixit/pipe-to-graphite)
a while ago to make it easy to record the output from the status
commands of gearmand, memcached, varnish, etc.  I don't know why we
never added it to the list of tools, so here it is.

Fix #403 #445 -- avoid creating the default profile at import time

`defaultUser` is no more. It was only needed for `getProfile`, which now
creates the profile on the fly.

The code also uses `Foo.objects.get_or_create()`, which is safer than a `try`…
`except` block around `Foo.objects.get()`.

The default profile is now created with an unusable password instead of a
random one, which avoids computing an expensive hash each time
`default_profile()` is called.
