Added a custom tag to display a link to a profile. Refactored the avatar tag to optionally display a profile link around the image. Removed the width and height attributes from the avatar image tag. I think this was causing disk hits whenever those properties were not cached. The avatar tag is now an inclusion tag.

tinyMCE.addI18n('en.advhr_dlg',{
normal:"Normal",
width:"Width",
widthunits:"Units",
size:"Height",
noshade:"No shadow"
});
