Previously when making a paste with a right click caused a crash because the location of the fake event was set to null.
This crash occurs only if the user didn't hit the keyboard yet.
Now, the location of the fake event takes the location of the last event of the app, who is the right click.
When the Edit menu is used to cut or to paste, Cappuccino needs to do all the work of making it happen. But the current code relied on the browser doing part of the work.
This fix adds new state so CPTextField can know if it should expect the browser to do some of the work or not.
Refs #1964.
This change brings nearly all copy and paste related into a single, self-contained class. This new class is still somewhat coupled to CPPlatformWindow+DOM.j in the sense that it's highly specific and meant to be called in a very specialised way. Despite this, it's still a significant decoupling and the new code is more readable and easier to follow.
