Change table component MIME type to text/csv (#1491)

With this change OMSimulator will support a subset of the proposed
MA-CSV standard for stimuli data. The proposal requires MIME type
text/csv for csv component, whereas OMSimulator previously used
application/table.

This commit ensures text/csv is used for export of SSPs. Importing SSPs
supports both the previous MIME type (to ensure compatibility with SSPs
exported in previous versions of OMSimulator) and the text/csv MIME
type.
