* Only auto set content-type if it has not already been manually set

* Add test

Note: this test fails with polendina in a browser environment as it has to create its own http server. But it demonstrates that the code works. Once the echo/info servers used in the other tests are updated to return the correct content-type, the test can be rewritten to use those and browser tests will also pass.

* Ensure manual content-type header override test only runs for Node.js

Unknown encoding fix (mikeal#80)

* Added code and test to deal with unknown compression methods

* Removed debug console logs
