Change setting of profile-dir
Fix tabtab for -- options

Add implementation of IOptionsService interface with one method - getKnownOptions. This method is used in commands service in order to get full list of supported -- options. As each CLI have its own list of knownOptions and the mobile lib has only some of them, the implementation of the interface has to be outside of the lib. This way we can use autocomplete for all available options, not only for the common ones.

Fix analytics timeout

Change dependency of xmlhttprequest to use Telerik fork.

Update common lib, where the following change is applied: EqatecMonitor.js call setTimeout of XMLHttpRequest with default value - 10000 ms. Add SetRequestTimeout method to EqatecMonitor which sets global timeout variable (currently this method is not used).

The timeout is required in order to prevent console hanging when analytics cannot send the request.
