Fix splitView options

[zzorba]

This change brings the SplitView controller in line with the rest of the V2 refactor. Introduces a new Presenter and an intermediate UISplitViewController+Options to apply changes.

I tested all 4 options, including with mergeOptions, and it seems to behave as expected.

So this seems to work -- though there appears to be something off with teh combination of split view + tab (but it might be a preexisting issue).

It seems to be related to the spacing for the bottom tab bar if I weld off the following bit of code in UIViewController+RNNOptions.h

- (void)rnn_setDrawBehindTabBar:(BOOL)drawBehindTabBar {
	if (drawBehindTabBar) {
		[self setExtendedLayoutIncludesOpaqueBars:YES];
		self.edgesForExtendedLayout |= UIRectEdgeBottom;
	} else {
		self.edgesForExtendedLayout &= ~UIRectEdgeBottom;
	}
}

to always execute the drawBehindTabBar=true path, then the extra spacing goes away. I think what should happen is the childViewControllers need to act as if they are NOT in a tab bar (from a height calculation POV), but I don't know the best way to achieve that.

Great feature! Thank very much!
I found several problems:

• statusBar.style option is ignored, global too
• Can we customize border between master and detail? Show/hide is enough.
• App is crashed on iPad when it started or moved to "split view" - when two apps showed simultaneously (for example 80% of screen is Safari, 20% my app)
