Add markup to control alignment of images and text

[elberet (Jens Maier)]

Supporting tables and automagically detecting baseline alignment in inline pictures are of vastly different scope… and while the latter would be completely out of place in a discussion forum, having tables sure would be nice, tho.

Too bad I suck with JavaScript.

However, we do plan to have a robust plugin infrastructure, so if someone wants to create the Discourse Super Mega Hyper Tables Composer Plugin… go for it.
