Add SCSS variable prefixes, default & use Bootstrap

[bertoost]

Please add a prefix to your SCSS variables.
Like $spinnerSize .. should be like;

$ladda-spinnerSize: 32px !default;

or even better $ladda-spinner-size (more like Bootstrap itself)

Also applicable for the theme file (colors etc).

Besides that; use Bootstrap variables too, with !default, like

$ladda-color-blue: $brand-primary !default;

And maybe even better to use bootstrap colors and names instead of something from yourself ;-)

After all; it's really a great addon for Bootstrap.
I use it for modal submit buttons which is working great!
