MenuViewController deselecting selected row when modal view controller opens.

[Lewion]

In iOS 4 to 4.3.2 this is a non issue.

For iOS 5: if you have selected a menu item and for instance in the next view controller on the stack you open a modal view over the entire page, the selected menu item isn't longer selected. Which is problematic for users to see what "head"' menu item they had selected. Every other view in the stack keeps it's selected state (also tableview) except for the menu.
