Added missing levels to logging menu

[NathanSalapat]

Added none and error options to the debug_log_level in the advance settings.

From conf.example:

#    Level of logging to be written to debug.txt:
#    -    <nothing> (no logging)
#    -    none (messages with no level)
#    -    error
#    -    warning
#    -    action
#    -    info
#    -    verbose
#    type: enum values: , warning, action, info, verbose
# debug_log_level = action

So seems correct 👍
