Combine code that finds mentions into one place and add hook points
Combined the code that finds mentions of other profiles into one place. common_find_mentions() finds mentions and calls hooks to allow supplemental syntax for mentions (like OStatus). common_linkify_mentions() links mentions. common_linkify_mention() links a mention. Notice::saveReplies() now uses common_find_mentions() instead of trying to parse everything again.
