Codestyle
Apply the metabox loading filter on the needed scripts too
Merge branch 'master' of git://github.com/Yoast/wordpress-seo into Filter-consistency
Typo

Using single quotes instead of double quotes
Doing attachment parsing in separate method
Making constructed if-else statement more readable
Related posts stuff
Improve design of related links box
Exclude current post from related links
Remove debugging
Limit to 5 instead of 10 to prevent overflow
Remove a lot of stuff, should be in premium
Remove from POT and minified files too
Include manual indexed tags into post tags sitemap

Checks noindex and include status for each term.
If 'index' and 'always' are selected for a term, this will include it in the 'post_tag-sitemap.xml'.

The old validation double checked variable type with useless functions like 'is_string()' while '===' does the same.
