zh_CN/*.lang.php re-worked

The legacy simplified Chinese i18n files from OpenX 2.8 were very much buggy.
These files are translated based on the latest version of en/*.lang.php, and saved with utf-8 encoding.
This is still an imcomplete version. But it is sufficient for working on most daily routines as the 'Default Manager' role.
Untranslated 'Campaign delivery' in openXReports plugin
Add zh_CN translatioin for five plugins

Again, these are incomplete, but are almost enough for daily work.

The five plugins are:
* openXBannerTypes
* openXDeliveryLimitations
* openXInvocationTags
* openXMaxMindGeoIP
* openXReports
