Add Ability to Filter Time by Client

This feature would be helpful as I use this drop down in myWA every time I have to run reports to make sure that time is logged to the correct project. 

Generally, everyone logs time to the correct client (e.g. Spectrum or UCI Merage), but time occasionally will get logged to the incorrect project (retainer vs site redesign).  Having the ability to filter by client will help catch when this occurs.
