Used on /documentation site only (for now) - should be of only limited use, as it does not buffer/cache the contents pulled from another page, and overuse could be seen as abusive by some web sites.
Allows the HTML main body from another web page to be embedded here. The <head><style><script> and much other HTML markup are removed before the sanitized (with the WordPress wp_kses function) HTML is embedded.
Use:
[embed_page url="http://example.com"]
If the page does not exist, a comment will be placed in the source of the page for diagnostic purposes.
