Support for combined button modifiers

[ezimir]

For example:

.is-primary.is-outlined.is-loading

produces

(you can see a faint loading indicator over the text)

Mmmh, must be an issue with order of the classes, because is-primary is-loading already works.

[ezimir]

More precisely, is-outlined breaks is-loading when the button has a color class, like is-primary.

These combinations are fine:
button is-primary is-loading
button is-primary is-outlined
button is-loading is-outlined (same as button is-loading)

This is not:
button is-primary is-outlined is-loading

is-outlined still breaks is-primary is-loading combination. And is-inverted too.

[jgthms]

Ah yes, you're right.
