1.7 to 1.8 Comment River Items

Hi all,

While most of you have probably see 1.7 as a distant memory, i've recently been prepping some 1.8 upgrades.

One thing I noticed was the comment river items weren't correct and some were non existent like 'page' comments.  Some comment river items, for instance the file, seem to use the 'river/object/file/create' river item rather than the 'river/annotation/generic_comment/create'.

Not exactly urgent as time goes to by it falls down the activity feed to where it probably won't get viewed anyway but would be nice to get to bottom of it if it is infact a bug. 

Has anyone else noticed this?
