Patch

Version:           1.0.0 (using KDE 4.4.5) 
OS:                Linux

When having 100+ contacts and going offline, UI locks for about 3-4 seconds.

Reproducible: Always

Steps to Reproduce:
Go online, and then go offline.

Actual Results:  
UI locks for about 3-4 seconds

Expected Results:  
UI doesn't lock.

It's caused by many onlineStatusChanged() method calls, and each call invokes a
DB query, that is performed by UI thread. My patch creates an additional thread
for Statistics Plugin that is responsible for querying the database. UI thread
leaves messages in a blocking queue, and DB thread queries the database.
