Fix tooltip when option is set to 'always'

[jespirit]

Fix typo with variable name. Just added _ underscore.

Changed this.alwaysShowTooltip to this._alwaysShowTooltip

bootstrap-slider/src/js/bootstrap-slider.js

Lines 809 to 812 in 88dfe2a

	else if(this.options.tooltip === 'always') {
	this._showTooltip();
	this._alwaysShowTooltip = true;
	}

bootstrap-slider/src/js/bootstrap-slider.js

Lines 1164 to 1171 in 88dfe2a

	_hideTooltip: function() {
	if (this._state.inDrag === false && this.alwaysShowTooltip !== true) {
	this._removeClass(this.tooltip, 'in');
	this._removeClass(this.tooltip_min, 'in');
	this._removeClass(this.tooltip_max, 'in');
	}
	this._state.over = false;
	},

Added a unit test.

Also there was a bug when options.tooltip was set to 'always' and the options.ticks_tooltip was set to true.
