import statement is uppercase, causing build-errors

[eBeyond]

When building an go-lang application using your middleware I get this message from go build:

package github.com/Sirupsen/logrus: case-insensitive import collision: "github.com/Sirupsen/logrus" and "github.com/sirupsen/logrus"

It's related to your import which is github.com/Sirupsen/logrus and not github.com/sirupsen/logrus.

package logrusmiddleware

import (
	....

	"github.com/Sirupsen/logrus"

	....
)

So I receive this message and logrus is imported twice. ;)

thanks
