Option to use the ignore options for g:ctrlp_user_command

* Not recommended as it'll likely increase the total indexing time and defeat
  the purpose of using custom commands, but should be an option for convenience.
  Also, mention the default (of not applying ignore options) more explicitly
  in the docs to reduce the number of unnecessary bug reports.

* Add a note about E706.
