Menu Counts and Packages

Sure these should have been two separate PR's but that's not how it worked out :dancers: 

1) this add the unapproved members and group counts to our moderation counts and shows in the menu as well as in the moderation action block
2) Adds link from the moderation area to unapproved members for better visibility, like any visibility
3) Tweaks to the .gz handler, in some cases it could fail to properly find the gz data start, this should fix that 
4) Tweaks to the .zip handler, it was off by 2 bytes that prevented comment extraction.  We don't use that so it was masked, but still wrong.
4) Checks when downloading by url, if the download is from a repo (git/bit) and renames the file to the repo name in no conflict mode.  prevents master.zip from repo a from writing over an existing master.zip from repo b since it will not save it as master.zip or master.tar.gz
