Standardizes the menuInputButton set usage to just use the raw action names rather than a middleman naming scheme for simplicity and standardization
Added comments to menuInputButtons.cs
Split out the menuInputButton containers to simplify and stabilize the code on the messageBox dialog
Removed old reference to script/gui files not there anymore
Simplified the input state check in guiGameListMenuCtrl.cpp
Added a check so we don't try exec'ing the selected list item in guiGameListMenuCtrl.cpp if nothing has actually be selected
