cjklib doesn't work with python 2.7

[unsermanninchina]

cjklib is outdated and does't work with python 2.7.

After updating to Kubuntu 12.04 which is using python 2.7 as standard all cjklib py-files in the plugins folder have expressions "sqlalchemy.exceptions" which has to be changed into "sqlalchemy.exc".
Python 2.7. doesn't know the former, so pinyin-toolkit can not start.

There is a patch at https://gist.github.com/2630334
