No longer needed because it has been merged into the core.
Track a change to proxy handling in Autobahn / twisted for #477. There's probably a more elegant way, but this works for now... Lacking a test, but have verified it locally.
We don't need the HTTPProxyConfig object at all anymore, just a `dict` will do.
Have seen this error a couple of times during live operation:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xa3' in position 1: ordinal not in range(128)
```
So commenting out that line. No idea how that character can appear in the relevant line, it's a £ sign.
Simplest fix for #481
This strips out unencodable characters and if not fixes, at least masks #483 by using `codecs.open` and telling it to ignore errors.

Whilst this doesn't break anything, it also doesn't seem to solve the problem, whose cause is currently unknown. |

This could be a Python2 issue, to be re-reviewed when we have migrated to Python3. |

Fix #483 by using
codecs.openand ignoring encoding errors. Seems a bit scary/naughty somehow - I would prefer to fix it upstream if I knew the cause.
