Since an id is used for the bestreply it simplified the removal of the parent li tags.  Also modified HTML markup for when a node was marked as a best reply to utilize the id 'bestreply-view' so that clearing/marking functionality is consistent across reloading pages/clearing caches, etc..

Split hook_node_view functionality with hook_node_links_alter to allow the comment's hook_node_links_alter to run before the bestreply's hook_node_links_alter function.  This will consistently render the 'View bestreply' link after the 'Add new comment' link.  Added an id of 'bestreply-view' for the default HTML bestreply markup as it differed from what was generated for a clicked marked best reply.  This fixes any issues with inconsistency when marking/clearing a bestreply on a node before and after the page has been reloaded.

added function bestreply_nodeapi.
