analogsea v0.4.0

NEW FEATURES

• Suite of new functions for tags: tag(), tag_create(),
  tag_delete(), tag_rename(), tag_resource(),
  tag_resource_delete(), tags(), and as.tag() (#117)
• Related to last bulllet: droplet_delete() gains new parameter tag;
  droplets() gains new parameter tag, and examples added to its man file
  for tag usage.
• New functions docklet_shinyserver() and docklet_shinyapp()
  to spin up Shiny server and a Shiny app, respectively. (#100)
• New function droplet_enable_backups() (#110)
• New function droplets_create() to create many droplets at once (#112)
• New function droplets_cost() to calculate cost of droplets across
  one or more droplets.

MINOR IMPROVEMENTS

• Added floating_ip_limit field to account() print method (#111)
• Improved description of name parameter for droplet_create() and
  docklet_create()

BUG FIXES

• Fixed problem with docklet_create() when port 22 is not open
  before further action is taken on the droplet. We now check if
  port 22 is open and error with informative message about waiting
  a bit for it to open (#113) thanks @fmichonneau @hrbrmstr
• Fixed problem in the print.droplet due to problem in droplet_ip() internal function (#109)
• Fix to *_create to allow flexibility in how often DO API is pinged.
  Previously we pinged every second, meaning you could hit your API rate limit
  fastish. Now you can set an option do.wait_time to tweak time
  bewtween pings to check for droplet creation (or other actions).
  See #108 (comment)
  for example of doing droplet creation in parallel. (#108) thanks @simecek !
• Fixed parsing bug in sizes() (#119)
