Quantum xml doesn't work with unicode

[Alex Xu]

When enable Chinese translation file and raise an exception that translated by Chinese will get exception as below:

Traceback (most recent call last):

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-4: ordinal not in range(128)

How to reproduce:
1. initialize or update template to chinese template

initialize:
python ./setup.py init_catalog -l zh_CN -i quantum/locale/quantum.pot -o quantum/locale/zh_CN/LC_MESSAGES/quantum.po

update:
python ./setup.py update_catalog -l zh_CN -i quantum/locale/quantum.pot -o quantum/locale/zh_CN/LC_MESSAGES/quantum.po

2. Translate a message of exception that you want to raise. There is chinese for test '中文中文'

3. compile catalog
python ./setup.py compile_catalog --directory quantum/locale --locale zh_CN

4. cp quantum/locale/zh_CN/LC_MESSAGES/quantum.mo /usr/share/locale/zh_CN/LC_MESSAGES/

5. running quantum with env varables: LANGUAGE=zh_CN:zh LANG=zh_CN.UTF-8 LC_ALL=zh_CN.UTF-8

6. then use quantum cli tools to raise the error that you have translated.

I can't reproduce this before. That was because I run quantum with eclipse, eclipse should have custom site.py. That change the default encode to utf-8, so I never can reproduce this bug. After I run quantum in console directly, this bug was reproduced.

If you can't reproduce this problem, please check your default encode by:

In [13]: import sys

In [14]: sys.getdefaultencoding()
Out[14]: 'ascii'

And ensure the output was 'ascii'

    Return unicode for object in json and xml serializer

    Fix bug 1160644
    Fix bug 1119790

    When try to serialize an exception object as json, it failed
    with 'ValueError: Circular reference detected' that is same error
    as bug 119790. So this patch fixes bug 119790 too.
