escape quotes for bash, furrealz this time

Any parameter in a job type template which is surrounded by quotes
will now be auto-escaped.

Examples:

job_type :foo, :template => "/my/cool/bin ':bar'"

every :day do
  foo %(single quote! -> ' <-)
end

will render to

@daily /my/cool/bin 'single quote! -> '\'' <-'
