Polylang 1.2.4

Here comes a new maintenance release with bug corrections: mainly some regression compared to Polylang 1.1.6 for very specific use cases and some PHP notices.

This version should also improve the user experience with multilingual content when using the theme customizer. It is likely however that it won’t be perfect for all themes as themes authors may implement functionnalities which bypass all filters. That’s for example the case of Twenty twelve with site title and tagline.
