Compare 2 specified versions, starting from left to right. If a part contains special version strings,
they are handled in the following order:
'dev' < 'alpha' = 'a' < 'beta' = 'b' < 'RC' = 'rc' < '#' < 'pl' = 'p' < 'anything else'

@static
@param {String} current The current version to compare to
@param {String} target The target version to compare to
@return {Number} Returns -1 if the current version is smaller than the target version, 1 if greater, and 0 if they're equivalent
function(current, target) {
            var currentValue, targetValue, i;

            current = new Version(current).toArray();
            target = new Version(target).toArray();

            for (i = 0; i < Math.max(current.length, target.length); i++) {
                currentValue = this.getComponentValue(current[i]);
                targetValue = this.getComponentValue(target[i]);
