move script directories for internal blender scripts.

ui/ --> startup/bl_ui
op/ --> startup/bl_operators

scripts/startup/ is now the only auto-loading script dir which gives some speedup for blender loading too.

~/.blender/2.56/scripts/startup works for auto-loading scripts too.

release/scripts/modules/console_shell.py
