Styling issues

[DethAriel]

Hi, nice job on the component!

The only issue I have with it right now relates to its stylability. Is there any chance that the styles currently in "styles" array could be extracted to a separate stylesheet?

The use-cases I'm envisioning include a) changing colors, heights, and stuff like that and b) create component themes (i.e. "tag-input.material.css", or "tag-input.bootstrap.css").

Any pointers to style the pills image and also to get rid of the "x" sign for certain items? Thanks in advance!
