Task manager

[Silvio Rhatto]

Task manager action and subcommands for keyringer:

keyringer <keyring> task ls     [status]          # list tasks
keyringer <keyring> task view   <id>              # get task details
keyringer <keyring> task new                      # create a task
keyringer <keyring> task update <id>              # edit a task
keyringer <keyring> task status <id> <new-status> # change task status

Proposed folder structure:

keys/tasks/<status>/id

Notes:

• Changing task status just moves the task file to a new folder.
• Encryption/decryption is done transparently using regular keyringer actions.
• Allow field definitions using YAML inside each task file.
• Milestones could be folders with symlinks to existing tasks or YAML files with task references.
