grateful 0.1.10

Fixed bug when matching citekeys with package names containing punctuation characters.

grateful 0.1.9

Fixed potential bug when matching package names with citation keys. Now using more strict regex.

New option output = "table" to produce a table with package names, version, and citation, to be used within an Rmarkdown document.

Now including package versions, besides package name.
For packages specifying more than one reference in their CITATION file, use all of them.
Rather than a list of package names, grateful now returns a text paragraph citing R and all the used packages, ready to be pasted in a manuscript or report.
Now including base R citation in all cases. Can optionally add RStudio too.
grateful can now be used within Rmarkdown. Including a chunk with cite_packages(output = "paragraph") will introduce a paragraph with in-text citations of R and the used packages, and their citations will be formatted when rendering the Rmarkdown document.
It is also possible to cite particular packages using their BibTeX keys generated by grateful. Or include them in the reference list without citing them in-text, using the new nocite_references() function.
New argument cite.tidyverse to collapse citations of all used tidyverse packages into a single citation to 'tidyverse'.
New argument dependencies to include package dependencies in the citation list.
