CRAN Release v0.8.25

• Use the curl option -T when uploading files to avoid out of memory
  errors with large files. (#544)
• The rsconnect.max.bundle.size and rsconnect.max.bundle.files options are
  enforced when processing an enumerated set of files. Previously, these
  limits were enforced only when bundling an entire content directory. (#542)
• Preserve file time stamps when copying files into the bundle staging
  directory, which then propagates into the created tar file. (#540)
• Configuration directories align with CRAN policy and use the location named
  by tools::R_user_dir. Configuration created by earlier versions of this
  package is automatically migrated to the new location. (#550)
