Percent is not encoded correctly in paths

[tdryer]

When constructing a path, a reserved character like space is encoded correctly by furl:

>>> furl('http://localhost').add(path=['foo bar']).url
'http://localhost/foo%20bar'

However, a percentage character is not encoded (and the following two characters are capitalized):

>>> furl('http://localhost').add(path=['foo%bar']).url
'http://localhost/foo%BAr'

In this case I'd expect the output to be:

'http://localhost/foo%25bar'

This bug is fixed in the latest furl v0.5.7.

>>> from furl import furl
>>> furl('http://localhost').add(path=['foo bar']).url
'http://localhost/foo%20bar'
>>> furl('http://localhost').add(path=['foo%bar']).url
'http://localhost/foo%25bar'

Update with

pip install furl --upgrade

Thank you for bringing this issue to my attention Tom. Don't hesitate to let me
know if there's anything else I can do for you.
