Fix Slovenian short date
Swap GlassTitleBar.png by dialogheader.png

This is only in MyWeather.xml
Swap textures, fix alignment and header fonts type and size

This commit swaps Glasstitlebar.png by dialogheader.png and makes
headers consistent everywhere.

Also fixes font types and sizes to be same in all headers

Aligns all headers label text to same height on dialog
* Swap textures
* Fix alignment on login screen and centre Header label
* Align header to centre to match remainder of header.

Admittedly a nicer font other than `font13_title` would be better but
which idk
