Check Overflow should make the Rapid button narrow too

[bhousel]

We have this nifty function checkOverflow in the UISystem which can check if we are overflowing the toolbars, and if so, class them as narrow so that the button labels can hide.

Rapid/modules/core/UiSystem.js

Lines 549 to 555 in fd4bd27

	checkOverflow(selector, reset) {
	if (reset) {
	delete this._needWidth[selector];
	}
	const selection = this.context.container().select(selector);
	if (selection.empty()) return;

It works pretty well, but we don't make the Rapid button narrow and we should.
Basically, just need to swap to a version of the Rapid logo without the wordmark next to it.

Done 💪
