Add analyticsTimeout option

When there's redirect in the request, XMLHttpRequest doesn't handle it very well and the console hangs for 10 minutes.
Add new option - analyticsTimeout - it is used to define the timeout for the features tracking operation. Set default value to 30 seconds. Modify AnalyticsService to call setTimeout before starting the operation of tracking. Add SetRequestTimeout method to EqatecMonitor which sets global timeout variable. Pass this variable to XMLHttpRequest instance.
This will not work if analytics-timeout option is used. I should check both options.
