This results in a fuckton of refactoring and code cancelling out
other code -- we no longer have a whole bunch of places trying
to support string params and array params, and doing their own
esaping and unescaping, never being quite sure if the data they've
been passed is escaped or not.
Also adds a bunch of type hinting, since we can now know what
data we're dealing with better.
Now with 17% less fat:
* Moved validation logic into OuroborosPost for sanity
* Added sanity checks for OuroborosPost values
* Changed defaults to be more sane (mainly tags)
* OuroborosPost now accepts an MD5 hash along the metadata (like it
should!)
* Fixed dupe handling logic
Due to how FILTER_SANITIZE_STRING works, if you had special chars in
your tags (eg. <3 or !) the string would be cut before the offending
character(s) and in worst case, result in no tags passing to the API
Also some code formatting and a redirect from post/show for clients such
as CartonBox so you can actually view the image after opening it in the
browser on the client.
