analogsea 0.5.0

NEW FEATURES

New function docklets_create() to create many docklets at once (similar to droplets_create()) (#120)
New volumes methods for the new block storage (aka volumes) https://www.digitalocean.com/products/storage/: volume, volume_action, volume_actions, volume_attach, volume_create, volume_delete, volume_detach, volume_resize, volume_snapshot_create, volume_snapshots, volumes, as.volume (#121)
New methods for new unified snapshots DO endpoints: snapshot, snapshots, snapshot_delete, and as.shapshot (#121)

You can now pass tags to the parameter of the same name when creating droplets, with either droplet_create, droplets_create, docklet_create, or docklets_create. The tags can be existing ones, or if not they will be created (#122)
Added more help on ssh keys to pkg level man file and to vignette (#115)

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.

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

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 https://github.com/sckott/analogsea/issues/108#issuecomment-151519855 for example of doing droplet creation in parallel. (#108) thanks @simecek !
Fixed parsing bug in sizes() (#119)
