install.pandoc - added "to_restart" parameter. With a massage to remind the user they should restart their computer after pandoc is installed.
Bump to 0.13.0

make checkMD5 issue warnings (maybe with a dialog box) instead of errors (since the current state of affairs is more hassle than it is worth...)
Updated some functions and documents in order to pass CRAN checks: RStudio_CRAN_data_folder, pkgDNLs_worldmapcolor, fetch_tag_from_Rd, add_to_.First_in_Rprofile.site, remove_from_.First_in_Rprofile.site, add_load_installr_on_startup_menu,README.md
Better use of "data" inside a function in a package.

Updated NEWS and manual for adding a packages= option to read_RStudio_CRAN_data.

read_RStudio_CRAN_data fails on out-of-memory (in the rbindlist call) if you've downloaded many RStudio CRAN logs.  This patch adds a packages= option if you're only interested in a subset of packages, which subsets the daily log data on the fly.  Other such filters might also be added.
