Fix guide to use correct number of files created by controller generator
Fix guide to use correct number of files created by controller generator

In e8546aba904fb6685ef2e61f1623c64e699a2c9c, the Getting Started guide
was updated to reflect the removal of CoffeeScript stubs being generated
by the controller generator. However, the comment above the table of
generated files wasn't updated, so it incorrectly remained "This creates
five files and one empty directory". This fixes it to now say "This
creates four files and one empty directory".
