Android keyboard support workaround code

[JohnnyFun]

Hi!

I noticed chrome android was setting which and keyCode to 229 since it's a soft keyboard. It seems like a relatively new thing they started doing. Anywho, I ended up just writing the following to make backspace and comma work on my android phone:

handleNonStandardKeyboards() {
	const input = this.taggle.getInput()
	input.addEventListener('keyup', e => {
		const key = e.which || e.keyCode
		const normalKeyboard = key !== 229
		if (normalKeyboard) return
		value = input.value

		//back
		const removing = value.length === 0
		if (removing) {
			const values = this.taggle.tag.values
			this.taggle.remove(values[values.length - 1])
			return
		}

		//comma
		const endsWithComma = /,$/.test(value)
		if (endsWithComma) {
			const tag = value.replace(',', '')
			this.taggle.add(tag)
			input.value = ''
			return
		}
	})
}

I haven't done extensive testing, but hope that helps anyone who runs into the same issue or someone who is more ambitious and willing to write a well-tested pull request.

So keyCode has been deprecated and when the next major version of this is released i'll drop support for ie 8/9 in which case I'll probably switch to e.key as mentioned in #67 a while ago. Testing on my android, there's still some things that need to be looked into (The input gets repopulated with the last tag text) but I've started experimenting here.
