Add support for side comments and inside a list comments.

Example:

softdepend:
    # We depend either ProtocolLib or ProtocolSupport
    - ProtocolSupport
    - ProtocolLib
    # Premium variable
    - PlaceholderAPI
    # Auth plugins
    - AuthMe
    - LoginSecurity
    - xAuth
    - LogIt
    - UltraAuth
    - CrazyLogin

Idea:
Implement those comments (and side comments) as a 'values comment' which is different from a 'keys/modules comment'
Example:

# This would be a keys comment
i-am-a-key: I am a value # This would be a values comment
