[aa2u] Fix bug: Make ‘M-x aa2u’ operate on accessible portion.

Regression introduced 2014-04-03, "Make ‘aa2u’ region-aware".

* packages/ascii-art-to-unicode/ascii-art-to-unicode.el (aa2u):
Take optional arg INTERACTIVE; add "p" to ‘interactive’ form;
when INTERACTIVE and region is not active, set BEG, END.
