• [x] use alt text for image size, for example: ![32x32](res://path/to/image.png)

Add CSS like syntax for some BBCode that don't have markup equivalent:

• [x] table css mix markdown

  @table=2 {
  |cell|cell|
  }

• [x] text alignment tags

  @center {
  Centered Text
  }

• [x] effects

  @wave amp=50 freq=2{
  Waving Text
  }
