added option to use em units for min and max font

[kevcenteno]

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:

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

Smelly. Refactoring as we speak.

@jhnwlsn do you think this is a good idea? Should I change anything?
