ggghost v0.2.0

CHANGES in ggghost 0.2.0 (accepted to CRAN)

• Allowed inclusion of supplementary data, with recovery (closes #3).
• Added a warning to recover_data when data object exists in the calling frame
  but has changed since being captured, with opt-out where used interactively
  (closes #4). Note that this is responsible for the less than 100% code coverage
  (everything except if (interactive()) is covered.
• Moved README supplementary objects out of package, reducing package filesize
  (closes #2).
