minor bug fixes in content translation module.


1. In  **“File”** & **“Page”** app after translation a page or resource the translated version is not visible to user this get resolved by setting an *access_policy* field.
2. Button text changed from **“Save”** to **“Save as Draft And Preview”**.
3. Uniformity maintain in all templates for *Language selection drop-down* as it shows only language name eg. English, ...etc.
