[pmg-devel] [PATCH pmg-gui 1/1] SpamQuarantine: fix download of large emails

[Dominik Csapak]

since datauri downloads are size limited (2MB in chrome), we have
to use another method, and instead of working around in the gui
(e.g. by using URL.createObjectURL) make use of the existing download
code in the api, which should have better compatibility
(and omits the whole raw -> json -> raw -> base64 conversion chain from
file to download)
