Anchorable Header not visible in generic theme for v4.60

[dgosbell]

There seems to be a bug in the generic template in the current 4.60 release where it does not display the Header for Anchorable panes

If I comment out the Theme in the TestApp in the following lines the Anchorable header disappears

AvalonDock/source/TestApp/MainWindow.xaml

Lines 69 to 71 in 9ffd291

	<DockingManager.Theme>
	<Vs2013LightTheme />
	</DockingManager.Theme>

Here is a screenshot showing the Generic cs the VS2103Light theme side by side

I've temporarily fixed this by rolling back to the 4.50 release which does not have this problem

It seems that 4.50.3 was the last version that did not have this problem and that it was introduced in 4.51.1.

Just remove the key from the style for AnchorablePaneTitle.

I also found the commit that broke this and commented on it.

good pickup @romen-h we could either remove the key or add an empty style without a key which is BasedOn the existing style. If I get time this weekend I might do a pull request for that second approach since it allows for the end user to easily re-use and extend the style that comes with the control.
