Implement caching for FindObject and GetComponentProperty

[AltTesterBot]

Problem:

When testing the project for VuCity I had to find all objects within a panel. In this case all objects have the same path until the last element but the Tester still searches from the root of the hierarchy every time the command is called.

Solution:

Add cashing to FindObject and GetComponentProperty commands.
