Update the 'log' command

- fully updates the log command to 0.9 styling
- fixes some argument interpretation bugs in 'log'
- adds a new 'none' type to 'log' (No type/timestamp)
- updates the meta information for 'log'
Fix a few typos

- the wrong function was being used to get a directory while defaulting
Denizen folders (My bad)
- an older command being displayed in dB.echoError() (I hadn't realized
'denizen stacktrace' was removed)
- some autoformatting
