#80: GetAddrHeader and SetGenHeader
This PR introduces two major changes: * SetHeader and SetHeaderPreformatted have been deprecated in favour of SetGenHeader and SetGenHeaderPreformatted As pointed out in #80 the naming was pretty confusing, given that we already have SetAddrHeader. With the new naming convention it should be more clear. For compatibility reasons the old methods have been kept for now but in reality they are just aliases to the new methods * GetAddrHeader and GetAddrHeaderString have been introduced As requested in #80 analogous to GetGenHeader we also need a similar method for the address headers. Since address headers are *mail.Address pointer, we've also added a *String method that will extract the address string and return a string slice instead Additionally we're introducing methods for the actual address headers: GetTo, GetFrom, GetCc and GetBcc (with a *String counterpart as well). This way the user has full flexibility. Either they use the more "low-level" GetAddrHeader method or the higher level methods for the corresponding address type
