BBcode help spoiler in editor

[metulburr]

I added a button to drop the BBcode help images in place. You can see this in reply/new thread editor. Maybe it will help some confusion as you do not have to move away from the editor to see the main points (our custom code tags)

Currently its all one image for input and one for output...
I want to make the images at some point more like reddit table of "you type this" and "you see this"...but i havent had the time yet to make it.     

EDIT:
for future ref, its in the codebuttons template
