set mergeFallback to true,

If your default locale is de_CH for example, then you get an incomplete list of locales. This issue has been resolved in the LanguageBundle and RegionBundle but not in for the LocaleBundle. Would be also a good idea for the CurrencyBundle

I renamed `flushOutput()` and `flushErrorOutput()` to `clearOutput()` and `clearErrorOutput()` since I find the current naming unintuitive. When reading [the blog post about this feature](http://symfony.com/blog/new-in-symfony-2-4-flushing-stdout-and-stderr-on-a-process) I initially thought that the output would be flushed to the console (as in `ob_flush()`).

Using "clear" on the other hand conforms well with [our conventions](http://symfony.com/doc/current/contributing/code/conventions.html).

I went through all components/bundles/bridges in symfony and searched for doctrine dependencies. Then looked if it only requires a subset (annotations instead of common for example).
