Issue #3334:

* Decrease connect timeout for donation state check from 30s down to 3s, so especially on application start noone has to wait too long only because heidisql.com is down again.
* Return TThreeStateBoolean in HasDonated(), so we can display an appropriate warning when the HTTP check was unsuccessful
