RETRYing 'til the morning

DatawRappr 1.2

Brings some bug fixes and some internal changes. Most noteworthy: The library now uses httr::RETRY to call the API. We will include an option to override the retry defaults by setting environment variables in the near future.

Bug Fixes

• Replace list.append to base append for ... in dw_edit_chart(). (fixes #59)

• Add transparent export option.

Enhancements

• most requests are now using RETRY() to connect. (thanks @fin, resolves #58)

• Allow to switch data upload type between csv and tsv. (599bfac, as proposed in #57)

• switched cat() to message(). (resolves #56)
