Set external encoding to UTF-8 to support unicode characters

[darthdeus]

Running scrolls list on my machine (pretty clean install of OS X Lion) dies with

/Users/darthdeus/.rbenv/versions/1.9.2-p320/lib/ruby/gems/1.9.1/gems/appscrolls 0.8.4/lib/appscrolls/scroll.rb:30:in 
`split': invalid byte sequence in US-ASCII (ArgumentError)`

This can be easily fixed by forcing external encoding to UTF8. It happens only on systems which don't have a proper locale set up (at least that's what I've observed.

$ locale                                                                                                       
LANG=
LC_COLLATE="C"
LC_CTYPE="C"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

The bug is also specific to Ruby 1.9, that's why there is a conditional on RUBY_VERSION.

This works for me. For some reason the twitter_bootstrap scroll explodes with error mentioned above. But this fixes it.

appscrolls 0.9.0

oops spoke too soon. This fixed the scrolls list but scrolls new still breaks for me on twitter_bootstrap.
@darthdeus Is it just the twitter_bootsrap scroll that blows up on you too, or are there others?
The issue must also be in thor.
