Redesign configuration

[devnote-dev]

The configuration file has been a bit of a confusing mess for a while, the following changes should make it clearer and easier to use:

• Repo:
• • Address: the repository address
• • The authorization token for the repository
• Panel:
• • URL: the panel URL
• • Key: the account API key
• • ID: the target server ID
• Files:
• • Include: a list of file paths or patterns to include
• • Exclude: a list of file paths or patterns to exclude
• • Backup: whether a backup of the current files should be made
• • Truncate: whether the current files should be removed
• Signal:
• • Kill: whether the server should be killed or stopped
• • Timeout: the amount of time in milliseconds to wait after sending the signal

The pre_run and post_run hooks will no longer be used. Repository authentication is still experimental.
