Add Left, Top, ZIndex property to EndlessGridViewModel. To remove error in debug. (MAGN-849)
These properties replace the EndlessGrid transformation for its position, seems to improve the frame rate during navigation.
Merge pull request #867 from l2obin/MAGN-849

This is a logical enhancement of previous implementation that made use of Transform (which is causing slight issue as per WPF performance guidelines). For that reason, I am accepting this merge in the interest of having it tested earlier.
