Title: rename plaintext cell -> raw cell

'raw' makes more sense to me as a name for these cells, regarding what we actually intend them to mean.

Raw cells should be *untransformed* when writing various output formats, as the point of them is to let users pass through IPython to their rendered document format (rst, latex, etc.). This is different from what is the logical meaning of 'plaintext', which would suggest that the contents should be preserved as unformatted plaintext (e.g. in a `

` tag, or literal block).

Before merging, we should decide what we should do about existing v3 notebooks which use plaintext cells. As this PR currently stands, these cells will simply be unrecognized.
