Customization - Context Menu for the AEScreen

The alert and event screen can be customized by adding customized extensions such as context menu items to the alert and event screen.

Open WinCC_OA_Proj/scripts/libs/aescustomizations.ctl, follow the TODO steps there and implement the interface for adding the context menu:

When Row Customization is enabled and you open the Alert and Event screen, the following message is shown: WCCOAui1:["DEMO active: initializeAesRowCustomization()"]
Click Start/Refresh to get the alerts (if your project has none, produce them). Right-click to open the context menu Demo. The menu item will be displayed:
Figure 1. Menu item Demo

and the following will be written to the log:
```
WCCOAui1:["CustomizeAesRow::addMenuItems"]["menuItems"][dyn_string 1 items
WCCOAui1:     1: "PUSH_BUTTON,Demo,1,1"
WCCOAui1:]  
```

When you click the Demo menu item, the following will be written to the log:

WCCOAui1:["CustomizeAesRow::handleMenuItemClick"]["functionId"][1]
WCCOAui1:["Custom menu clicked: "]["functionId"][1]["selectedRows"][mapping 2 items 
WCCOAui1: 0 : mapping 60 items 
WCCOAui1: "#52" : -?- 
WCCOAui1: "abbreviation" : 3

WCCOAui1: "#38" : -?- 
WCCOAui1: "priority" : 40

WCCOAui1: "#59" : -?- 
WCCOAui1:]

When the Row Customization is enabled and you open the Alert and Event screen:
```
WCCOAui1:["DEMO active:
initializeAesPermissionCustomization()"]
```
Click Start/Refresh . When you click the row(s), the following will be written to the log: WCCOAui1:["CustomizeAesPermission::hasAccess(1, 1, 1)"] WCCOAui1:["CustomizeAesPermission::hasAccess() returned TRUE"]
