define ess-julia group and make inferior-julia-program-name custom variable
dont setq-default inferior-ess-program
don't activate eval-visibly menu if process cannot handle it (aka inferior-ess-secondary-prompt is not defined)
cosmetic
fix the startup message for non-R dialects
correct julia's sintax table to syntactically fontify strings
adjust julia's prompts
use "include" instead of "require" and adjust imenu regexp in julia
make julia's default ess-eval-visibly 'no-wait (julia cannot evaluate visibly)
don't play with local ess-eval-visibly (bad idea). Just check directly in ess-send-string if process can evaluate visibly or not.
