New Dialog Widget Option: Close Button

[Audacitor]

Dialog widgets should have an additional option that allows the developer to choose whether or not the dialog has a close button. The lack of a close button can be useful in circumstances where the dialog is the main window, and needs to be on the screen at all times.

Some may feel that this undermines the purpose of the dialog widget, in the same way using a table based layout undermines the purpose of a CSS layout. Dialogs should be for presenting information, not acting as application windows. In this case, perhaps the addition of a window widget should be considered instead.

Use CSS to hide the close button.
