rhub 2.0.1

rhub now avoids a message from recent versions of the R6 package, about the finalize method of an R6 class having to be private.
Using platform aliases works correctly now when selecting platforms.

rhub 2.0.0

This is a completely new system, see ?rhubv2 manual page or the ‘Getting started with R-hub v2’ article at https://r-hub.github.io/rhub to start.

Previous functions are now deprecated and defunct. They will be removed in the next version of the package.

Replace platform parameter with platforms in check() (#497).
Update shortcut for Mac OS platform (@echasnovski, #393)
cran_summary() now works even if there is a NOTE/WARNING/ERROR in one platform and nothing on other platforms (@fabian-s, #259).
Check results have now a get_ids() method, to easily query the id(s) of the check.

cran_summary() now messages that we recommend to fix all NOTEs, WARNINGs and ERRORs before a CRAN submission when the check results aren’t 0 NOTE, 0 WARNING, 0 ERROR.
cran_summary() now outputs informative messages when any of the builds of the group hasn’t completed (yet, or at all).

cran_summary() now works for packages whose R CMD Check result include no NOTE/WARNING/ERROR, and gives an informative error message when not all builds are completed yet.
cran_summary() now prints lines to screen without unwanted indentation.

New local_check_linux() function to run an R-hub check on the local host’s Docker. New local_check_linux_images() function to list R-hub Docker images.
New check_on_solaris() shortcut to check on Solaris X86, without building the PDF manual or the vignettes.
New get_check() function that works with check ids, or a check group id.
list_package_checks() and list_my_checks() now output a tibble, that is nicely formatted when printed to the screen.
The output of get_check(), check(), check_on_, check_for_cran(), etc. functions gained
- an urls() method returning a data.frame with URLs to the html and text logs, as well as the artifacts, of the check(s);
- a browse() method replacing the web() method for opening the URLs corresponding to a rhub_check object.
New cran_summary() method to print a summary for a group or set of checks.

In printing methods the submitted time is now always correct thanks to explicitly specifying units for as.numeric.difftime (@jimhester, #94 and @schloerke, #135).

First public release.
