Santhosh Thottingal f11ef736a4 Fix the logic of apply and cancel actions ...

* Refactored the Cancel button handler code to cancel method in
display settings and input settings.
* When the user makes changes in multiple modules and clicks the Cancel
button or closes the language settings after that, cancel the changes in
all the modules. See bug 50564.
* The Apply button was always active in input methods module. Fixed the
logic for that.
* Renamed the enableApplyButton method to markDirty in both modules.
* Introduced isDirty attribute to the modules for optimizing the Cancel
method to avoid unnecessary restore actions.
* More minor cleanup and documentation.

Bug: 50564
