Long titles fix

appDisplay.js: set the maximum label length in the menu item to 50 characters workspace.js: set the maximum width of the title equal to the border width if it is larger

This problem happen on two areas, the overview and the apps menu when the title of the window is too long. The titles simply fill the screen and even sometimes go beyond it..

This will just limit it to the width of the window in the overview, and to 50 characters in the app menu.

You can see the issue with screenshots here as I first made an extension to fix this problem: https://github.com/Naheel-Azawy/gnome-shell-extension-overview-titles
