Title: added option to use em units for min and max font

This allows for using 'ems' for minFont, maxFont, minimum, and maximum, via a useEm boolean. fontRatio and lineRatio is essentially untouched A dirty example of usage would be:

```javascript
$('#em').flowtype({
minimum: 31.25,
maximum: 75,
minFont: 0.75,
maxFont: 2.5,
useEm: true
});
```
