This is a maintenance release that provides provisional release of a few bits of new functionality.

New Features

New functions characterize() and factorize() provide methods for converting "labelled" variables (e.g., from Stata or SPSS) into character or factor variables using embedded metadata. This can also be useful for exporting a metadata-rich file format into a plain text file. (#153)
export() now sets variables with a "labels" attribute to haven's "labelled" class.
Added a new function spread_attrs() that reverses the gather_attrs() operation.
Add .bib as known-unsupported format via bib2df::bib2df().

Expanded test suite and increased test coverage, fixing a few tests that were failing on certain CRAN builds.
