Updated help, merged all module admin pages
into one file and all supervisor pages also into one file,

Changed overview page to reflect above merges

Chnaged help.xml to reflect changes too.

Haven't yet updated search help (as I havent seen it).
WL-2877 Update to use id's instead of anchors.

This reduces the size of the html and also doesn't affect the styling.
Merge branch 'WL-2877'
