Does not react to TryExec file changes at runtime

Slingshot does not react to creation, deletion or executability change of files specified in TryExec field of .desktop files. Only restarting it makes it update TryExec file status.

Slingshot should watch creation, deletion and executability changes of files specified in TryExec field.
