Experimental alignment layout manager using a property on the views

Herein lies an experimental layout manager which aligns the child views based on the value of the 'align' property of the view. The view can be aligned to the top, bottom, left, right or content. (set align() to None if the view is not to be considered for alignment).

Eventually, the align() property should be turned into an AlignAtrribute class that is then dynamically attached to each view instance that wants to be aligned. The "None" enumeration element could then be removed since the *lack* of the AlignAttribute would be the same as "None".

those values here
