[GTK3] "What's New" and "Top Rated" tiles have different widths

This is a consequence of the change I made to the tiles to remove the word 'reviews' and add the number of ratings in brackets after the stars. At the time I made a change to dynamically size the tiles so that they were at least as big as the widest 'stars + ratings + icon + padding' combined width. This can be different for each tile though.
We'll need to find a happy medium (i.e. maximum size of the widest tile on display needs to be the size of all other tiles on display) in order to ensure the tiles are all the same size, but this will result in some tiles having far more whitespace than others.

With the exception of the icon in the FeaturedTile, everything is text, which means we should just be able to set the width request to some multiple of the current em-value....

ok, linked branch has an approach i think should def work... featured tile width is derived from a global, so aaron your approach is maintained except we only use the calc'd req_width if it is larger than the current global featured_tile_width value

along the lines of:
global _featured_tile_width
_featured_tile_width = max(req_width, _featured_tile_width)

all featured tiles throughout software center will have the same width as a consequence of this change. Hope this is desirable.

I think the minimum width could do with an increase of 30% or so ... but testing r2144 of that branch, it does seem to fix the bug described here. Thanks Matthew!

Branch merged, thanks Matt!

This bug was fixed in the package software-center - 4.1.21
