Crashes for multiple project targets

[mogol]

Hey,

There are two targets in project. So, I have in Rambafile

# The main project target name
project_targets: Dev.Target,AppStore

When do

generamba gen MyAwesomeList template_name

I got

/Users/gsaprykin/.rvm/gems/ruby-head/gems/generamba-1.2.0/lib/generamba/helpers/gen_command_table_parameters_formatter.rb:10:in `prepare_parameters_for_displaying': undefined method `join' for "Dev.Target,AppStore":String (NoMethodError)

There is a bug in docs. Should be

# The main project target name
project_targets: [Dev.Target,AppStore]
