Merge pull request #8 from mimosa67/master

Added sudo, quick check through especially formatting
Rename htmlsep rule to html

Rename the old html rule to htmltmp, as it is only used as a temporary
rul and rename the htmlsep rule to html. It's used all the time, so it's
better if we kept it shorter.
Fix some NOTE and IMPORTANT sections
Comment out the rEFIt comment
Move reposetup section to a more appropriate place
Remove some formatting that wasn't needed
