v2.0.0-dev1

This release adds support for the \cxplvrortho control word, which allows Plover to do orthographically-aware attachments. This is incompatible with previous behavior, in which all attachments were considered ortho-aware. Now \cxplvrortho has to be specified in order to be treated as ortho-aware.

{\*\cxs EURB}{\*\cxplvrortho}\cxds ish       ->  "EURB": "{^ish}",
{\*\cxs *EURB}\cxds ish                      -> "*EURB": "{^}ish",
