Title: Whitelisted th and td to fix #79

``HTML_SANITIZE_OUTPUT`` breaks alignments in tables.

So, the input with ``HTML_SANITIZE_OUTPUT`` flag:
```
| Tables | Are | Cool |
|----------|:-------------:|------:|
| col 1 is | left-aligned | $1600 |
```
will lead to the result:
```

Tables
Are
Cool

col 1 is
left-aligned
$1600

```
instead of:
```

Tables
Are
Cool

col 1 is
left-aligned
$1600

```

As @mprobst [pointed out](https://github.com/russross/blackfriday/issues/79#issuecomment-49731427) it can be fixed by white listing "td: align". Moreover, "th: align" should be white listed as well.
