Add support for reading data from $_SERVER variable

[ocean90]

PHP dotenv v5 has switched to using the $_SERVER global as the default storage instead of the putenv() $_ENV variable (see v4 fallback chain). See this comment by @GrahamCampbell for the reasoning behind this change.

What are you thoughts about adding a new Env::USE_SERVER_ARRAY option which reads the data from the $_SERVER variable?

Not quite. We've been using $_SERVER, $_ENV, and putenv since v1. v5 drops putenv by default.

option which reads the data from the $_SERVER variable?

Yep, this is where env variables actually are, and has always been the correct place to look.

@ocean90 I've added this option to env v2.1 (not released yet).

Thanks! Was just going to submit a PR with the same changes. 😃

Note that stripping quotes will certainly not be relevant for files loaded by phpdotenv. Quoted strings are processed without their quotes, already. Any quotes that appear would have been intentionally escaped by the user.

@GrahamCampbell I see, but this library is independent of how the variables are loaded. Some use phpdotenv, others another library or not library at all. Anyway, this is configurable.

New version released. Thanks guys!
