Added process of booleans

[jaumarar]

If the .env file has a boolean value it will be parsed into the correct type:

.env file:
VARIABLE=true

Before:
$_ENV['VARIABLE] = 'true';

Now:
$_ENV['VARIABLE] = true;

• Also added test and make this option configurable via DotEnv::PROCESS_BOOLEANS.
• Attribute @runInSeparateProcess has been added to the test to restart $_ENV variables

I approve the changes but I have a few remarks:

• In processValue declare argument type as string
• In load function , is not necessary return the values that have been loaded into ENV

Thanks

Perfect, I think all changes have been made

Ok for me , thanks

You are forget to remove unit test about returns values :

/**
* @runInSeparateProcess
*/
public function testLoadReturnsValues()
{
$loaded = (new DotEnv($this->env('.env.return')))->load();

    $this->assertEquals('returned', $loaded['VALUE']);
    $this->assertEquals('returned', $_ENV['VALUE']);
}

test failed
