HorizontalAlignment of BaseMetroDialog content

[pfattisc]

What steps will reproduce this issue?

The original dialog (note: the content is 'spread', i.e. the space between the left corner of the dialog's title and the buttons in the right bottom corner):

The problem is that the "stripe", where dialogs are presented in, is separated into three columns (width: 25*, 50*, 25*) and the dialog's contentpresenter resides in the middle column.
So if the custom content isn't spread all over the content area, the alignment of the content seems left orientated (since the first column width of 25* is relative and won't grow)

Content seems 'left orientated' (Note: Space on the left side of the content is less than the space on the right side of the content)

To fix this the HorizontalAlignment of the 'core" grid (the one that hosts contentpresenter and PART_Title) should be HorizontalAlignment="Center".
So can you (=> bind to parent HorizontalContentAlignment).

Expected outcome

It should be possible to set alignment of a BaseMetroDialog's content.
Frankly, just bind the HorizontalAlignment of the 'core grid' to the BaseMetroDialog's HorizontalContentAlignment in the controltemplate.

Expected Dialog (note: the whole content is center aligned):

Repo

None :-(

@punker76 Unfortunately the changes produce not the expected outcome. The problem is that the content is aligned but the title isn't.
Either the title should be aligned the same way (template binding) as the content or there should be an extra property to set the title alignment.
Right now, if I change the HorizontalAlignment to "Center" the content is aligned as expected but the title stays on the left side, which looks awkward.
