Changes to go-sawyer are breaking build

[zhemao]

Getting the following error message on go get

package github.com/lostisland/go-sawyer/mediaheader
    imports github.com/lostisland/go-sawyer/mediaheader
    imports github.com/lostisland/go-sawyer/mediaheader: cannot find package "github.com/lostisland/go-sawyer/mediaheader"

It appears that go-sawyer has changed its structure and the mediaheader folder no longer exists.

Same here, tried to follow #59 but as a complete novice, I have no idea on what should I do.

Did you figure it out, @zhemao?

Tried those instructions, and they worked, but there's something to be said about playing nicely with go get. It would be much simpler to just depend on a clone of go-sawyer which is rolled back to the needed version.

#64 should fix this problem
