Merge pull request #9 from percipia/header-format

Change how we are formatting headers for sendevent and sendmsg

Switch away from using http.Header.Write() due to it stripping \n

This is needed for some header strings that need to be sent to FreeSWITCH. For example the `extra-headers` header used in `sendevent NOTIFY` when providing a contact URI or the to/from URIs.

This change makes the following header possible:
extra-headers: Messages-Waiting: yes\r\nMessage-Account: [email protected]\r\nVoice-Message: 1/0\r\n

The main tradeoff here may be an increase of time building the header string. However when testing this out the difference was within microseconds and within error margins.
