Fixes issues with post editor removing the image

This reverts commit 89baaf0a5e.

Yeah this was a terrible idea

Add wakapost merging to add fields from the request to the original post

staff.check_password -> StaffMember.get_from_cookie
board.check_access -> StaffMember.check_access(board_name)
admin_task_data -> admin_data
admin -> cookie (when it refers to the cookie)

All aboard the technical debt train, choo choo.

Next station: more untested code rewriting.

There's no option to remove the limit.

This file move is resposible for thumbs getting left
behind when trying to delete spam.

This typo has been around since forever

With some micro brown paper bags. I can't into IME

Now commands such as rebuild_cache can be used from commandline, and
display a useful help message when there are missing environment
variables

Includes port number now

Happened with the bug fixed in the previous commit, a WakaError raised
from a template resulted in 500 internal server error

Conflicts:
	board.py

Gotta go fast.

Conflicts:
	app.py

Let's hope pyflakes didn't fuck up. I wish I had finished those unit
tests already.

The best database ever.
