Standardizing and shortening the WP security escaping functions.

attribute_escape() is now esc_attr()

Additionally, you can do attribute escaping and translation in one go. Just add the translation function to the end. Like so:

  • esc_attr__() — translate and return, attribute-escaped.
  • esc_attr_e() — translate and echo, attribute-escaped.

Will be following up with esc_html (with __() and _e() variants), esc_url(), maybe some more. Will be nice, short, predictable, and allow you do translate/escape in one go without a lot of nested parenthesis.
