custom Icon can be loaded from search directory

[Varaprasath]

Currently Custom Icon can only be placed under 

C:\Users\Public\Documents\National Instruments\TestStand 2014 (32-bit)\Components\Icons

and

C:\Program Files\TestStand 2014\Components\Icons

and also from 

search directory option for icon (New Idea)

If icons can also be loaded in path mentioned search directory, It help a lot in handling things among a large ATE Team (50 Test Developers)
