Nodecomment incorrectly assinging it's node/add access callback to EVERY content type

I was working on a module that needed to override the default node/add access for a specific content type. I added my own access callback for this content type using hook_menu_alter, but noticed it wasn't be fired. If I changed the weight to my module to 1, it worked correctly.

I started investigating and found that nodecomment module adding it's own node access function "_nodecomment_node_add_access" to every content type for the path node/add/[content-type]. After reading thru your modules implementation a bit, I think the intention was to just add the custom callback for node types that utilize nodecomments for comments, NOT for every content type instead.

I patched this to only add the access callback "_nodecomment_node_add_access" for the proper content types.
