A fix size is not friendly with a responsive design

[lestcape]

By reading the "README.md" we can think that this project want to target the bootstrap framework some how or at less be compatible with it. Unfortunately the plugin works by moving a preset image in the background which forces the kv-score bar to have a fixed size, losing the opportunity to really be responsive.

Fortunately it is very easy to stop using a background image and instead set a background color for the score box avoiding the need to set a width and making the plugin friendly with a responsive design.

Please see some ideas of how to implement the background color of the kv-score box, without the usage of an image here:

Example:

This is an example of how i fixed this problem from outside the plugin, without to touch the code, but for sure will be preferable if strength-meter is already prepared to work with percentages and not with a fixed box width.

Thanks for the feedback. This project was done years back. Will definitely look into your suggestions when I get time.
