Updating TextInput widgets to enable text editing

[Opus4]

I wanted to point out this change in the v7.1.3 beta regarding TextInput widgets, allowing the use of arrow keys to move around, stop/backspace to delete the character to the left of the cursor, and delete to delete the char to the right of the cursor:

The mouse can also reposition the cursor as well. TextInput fields that have text wider than their visible space are also now offset and rendered appropriately. These new capabilities are controlled by the "Focusable and Cursor" property in the TextInput Widget (it is off by default for legacy support reasons).

The default STV has converted all TextInput widgets enable the new "Focusable and Cursor" widget property (if a TextInput widget doesn't have that checked, then it is controlled by a themed version of the widget that does have it checked).

Any custom STVs or plugins that enable that widget property should also disable the display of its own cursor for the input field (since the core now draws one itself) and change the Panel & TextInput widget sizes -- previously, at least in the default STV, a TextInput widget would just be wide enough to enter the entered text, then display a cursor next to it. Now, the TextInput widget uses the full width of its parent Panel.

And, until the "Focusable and Cursor" widget property is changed in Studio, the TextInput should continue to function as it did previously.
