double values are serialized with commas as decimal points

Might be related to #51. As a workaround I can start my application with LC_ALL=C, but this is obviously something that should be fixed in the library. I'm using git master.

Hi @jplatte, which locale are you using when the bug occurs?

It's time to approach this issue...

[jplatte]

Not sure exactly how locale identifiers in std::locale correspond to the various locale variables on my system, but it should be something like de_DE.UTF-8, de_DE.utf8 or just de.

I created a branch with a fix: https://github.com/nlohmann/json/tree/issue228

@jplatte Could you please check if this works for you?

[jplatte]

It does work. Thanks!

@jplatte FYI: I now merged the PR.
