[PATCH v2] post-receive-email: explicitly set Content-Type header

[Alexey Shumkin <zapped@mail.ru>]

Some email clients (e.g. claws-mail) incorrectly display
message body when there is no Content-Type header and charset
explicitly defined.
So, set explicitly Content-Type header and charset
can be defined with hooks.emailcharset config variable.
