Added $toolsServerSync, other small bits and bobs

$toolsServerSync() added, for now all posts are synced to the tools
server. this will give access to IDs, and tools images not needing to be
in posts in the future.
Added $toolsGetVal(), $toolsSetVal() and $toolsDeleteVal() as aliases of
the same GM functions to make swapping to jQuery storage (if we do)
easier.
Started the Serv panel, and image upload form.
tools now tracks postnumber of successful posts.
