Compute line height if `options.lineHeight` is not provided

[aron]

Should be able to use $root.css('line-height') for a best guess right?

Or as a non jQuery dependent solution something like this might do:

var style = window.getComputedStyle(el, null);
var lineHeight = parseFloat(style['line-height'])

Is it a required parameter for performance reasons or something? If I submitted a pull request to make line height optional and auto-detected if not provided would it be accepted?

Yes definitely would consider it! Just got to make sure it's cross browser compliant

getComputedStyle is one of the most expensive javascript property. This will kill rendering performance on a page using 100+ truncation.

@NoxHarmonium @aron feature available in truncate.js v1.1.0, enjoy!
