[PATCH] Add 'inline-only option to org-export-babel-evaluate

[Aaron Ecay <aaronecay@gmail.com>]

* lisp/ob-exp.el (org-export-babel-evaluate): Update defcustom to
  provide 'inline-only option
  (org-babel-exp-results): Implement 'inline-only for
  org-export-babel-evaluate

This is useful because there is no way for inline results to be stored.
The imagined usecase is that all non-inline source blocks will be
evaluated manually by the user.  Inline blocks, however, must be
evaluated during export, or they will be simply deleted by the exporter.
