make jshint task friendly as a multitask
Make options default for all targets (less, handlebars, jst, uglify)
Merge branch 'default_options_for_targets' of git://github.com/jasonkarns/lineman into jasonkarns-default_options_for_targets
Sadly, jshint doesn't appear to be very happy when
used as a multitask. It just explodes. Upgraded it
anyway
