Various changes

- moved updateCOnfiguration slot to Application class from MainWindow (its right place)
- loaded conf out of ctor (this will increase boot speed, but could in theory let rekonq fails on first load. We'll see..)
- set accept-language (raw) header. RFC 2626, section 14. Choose your preferred language.
- Try fixing CacheControl values (rekonq seems work quite well offline, now)
