bbcode [b] button misaligned across themes

[cburschka]

I don't know when this first crept in (definitely <1.4 release), but the [b] button is positioned several pixels lower than the other ones. Screenshots:

And so forth.

(It's also vertically smaller than the others.)

... I could swear I'd have noticed that kind of error, but apparently it's been there all along. All the way back since the styles were first added to this repository.

Oh well, high time to fix it.

Experimenting shows that this is a direct effect of font-weight:bold.

This has to do with line height, vertical alignment, and other things.

There might be a better fix, but this seems to do fine:

#bbCodeContainer button { line-height:1.4em }
#bbCodeContainer button[value=b] { vertical-align:bottom }

(note that aligning all buttons to the bottom will move the entire row up; for some reason it works if only the [b] button is bottom-aligned.)

Now the b is a bit higher up than the other labels, but that's less noticeable than the button itself being misaligned.
