Revert detection of page templates to 3.3 functionality.

WP_Theme in 3.4.0 used get_file_data(), which is far too strict when
compared to the original regular expression in get_page_templates().
This causes missing templates when, for example, the PHP comment
starts on the same line as the header.

see #20955 for 3.4.

When looking in a sub-directory of wp-content/themes for more themes, check
if that specific directory exists before looking inside of it for style.css.

If a plugin triggers the WP_Scripts constructor prior to init, fire wp_default_scripts()
then and again on init.

Only add our localized strings once we've fired init, in case we do have the situation
where we fire wp_default_scripts() twice.

Fixes issues where plugins or themes try to enqueue a default script handle prior to
init. Does not allow #19959 to regress.

fixes #20971 for 3.4.
