Add a touch control visibility screen. All touch controls can now be toggled on or off, except for the Pause button on platforms that have it, as a safety precaution.
Adjust a couple styling issues.
Make Toggle All actually function.
Make non-image Choices translatable from the MappableControls section.
Add TouchControlVisibility.cpp/h to Visual Studio project "UI".
Remove rebase junk, update CMakeLists.txt, update Android.mk.
Make the header and Control Visibility texts translatable.
Default to true for all touch control visibility, and actually translate Control Visibility.
Fix Android build, adjust includes.
Make the text and images centered.
Merge pull request #4252 from thedax/touchControlVisibility
