SeverRequest::fromGlobals only works on Apache

[Tobion]

SeverRequest::fromGlobals only works on Apache as getallheaders does not exist on other webservers as @iotch pointed out in #54 (comment) and I can confirm. So the headers are not available then.

We can provide a fallback solution reading the headers from $_SERVER (in an ugly way). This is also done in symfony etc. Maybe it's a good idea to implement getallheaders as Polyfill and add it to https://github.com/symfony/polyfill

This could probably works https://github.com/ralouphie/getallheaders

can we implement a simple (ugly as you call it) solution to start with like here which will be part of the library so we do not have to include other libraries for this?
