organize examples

This commit is largely based on work by Thiago Arrais (@thiagoarrais)
and Shane Bradfield (@l33tLumberjack). I wasn't really able to get their
PR reasonably merged onto the latest master, so I reapplied their changes
manually here and did some further improvements on that.

+This example builds on mitmproxy's base proxying infrastructure to
+implement functionality similar to the "sticky cookies" option.

+Heads Up: In the majority of cases, you want to use inline scripts.
