Option to open print preview in new tab instead of new window

[DerZyklop]

Is your feature request related to a problem? Please describe. Yes. Some browsers print menu size orientate on the size of the window that should be printed. If the new Tab opens in a very small tab, the print menu size is very small. Therefore we want to open the preview in a new tab, so we ensure that the window-size is as large as the window with the ngxPrint thingy.

Describe the solution you'd like An option like printPreviewTarget="tab" or printPreviewTarget="window" which default is window.

In issue #41 , @usmansaleh talks about a problem, where the preview always opens in a new tab.

@usmansaleh, is this a mistake, and you meant window or did you manage to open the preview in a tab?!
