(1) Improved startup responsiveness during first time installation
(2) Async update app list for better responsiveness
(1) There is chance that the taskbar might auto start itself.
(2) Items installed while taskbar is turned off are not shown properly in app list.
(3) Not able to use swipe mode (On some devices) when Trigger side is set to left (I will fix in next release)
(4)App list is empty after upgrading from market. (Stop and restart taskbar to solve it)
