User control over file encoding

[1000TurquoisePogs]

As a mainframe user, I want to control the encoding when sending & receiving data, so that I get data that is useful on both workstation & mainframe.

Acceptance criteria: ability to choose encoding for download & upload. For download from mainframe to workstation, utf8 or binary(no encoding change) are the minimum required choices. For workstation to mainframe, the content can either be transferred as binary (no encoding change), or you can choose to have a conversion to utf8, ebcdic-1047, ebcdic-931, or iso-8859-1.
Acceptance criteria: ability to choose whether to tag on upload to mainframe, or not. Default=yes
Acceptance criteria: download from mainframe is assumed ebcdic unless content is tagged
Nice to have: be able to view the tagged encoding of a file on the mainframe as a detail column
