Theme Developers - include header and footer hooks

[n00dles101]

get_header & get_footer trigger the theme_header & theme_footer hooks as of 3.0

Going forward with 3.1 they will also trigger script queuing for including javascripts/stylesheets with your plugins/themes.

we are asking they are included so we can be sure these 2 hooks are triggered.
There have been several problems with plugins on the forum that are down to theme_header not being called.
