Release 0.25

Perlbrew Release 0.25

Big congrats to p5p for releasing 3 branches of perl5 in the same week!

perlbrew 0.25 is basically a bug-fixing release with some small improvements

• suggest when user types wrong commands
• Improvements about self-upgrade
• exit with non-zero status code when there's some sort of error
• Added verification of existing alias before attempting unalias
• Fix install-cpanm for those who uses curl

Command suggestion

Now when you have a typo in your command names, perlbrew shows you a list of suggestions

> perlbrew lixt
Unknown command: `lixt`. Did you mean one of the following?
    list
    init
    alias

Thanks Rob Hoelz for the implementation.
