outdated helptext for ipfs log level

[boozook]

ipfs version 0.4.0

# ipfs log level all info
Changed log level of '*' to 'info'
# ipfs log level all fatal
Error: logger: invalid log level
# ipfs log level all panic
Error: logger: invalid log level

But help says:

ipfs log level --help 

    ipfs log level <subsystem> <level> - Change the logging level.

ARGUMENTS:

    <subsystem> - The subsystem logging identifier. Use 'all' for all subsystems.
    <level>     - The log level, with 'debug' the most verbose and 'panic' the least verbose.
                One of: debug, info, warning, error, fatal, panic.

And one question: How can I check if daemon is alive?

It looks like that help text is out of date, there arent fatal and panic levels anymore.

As for best way of checking daemon liveness, i normally run ipfs id and make sure that the addresses field isnt null. Having addresses there means your node is online.

@whyrusleeping Thank you. I now do it that way.
