Fix for a metatables crash when using the buff manager.

Fix for wrong text alignments on the ammo counter widgets.
When showing ammo in clip using the heat bar and at 0 ammo hide the leftover bit of heat bar that was visible.

Added command /ut_preset_page that fetches a page of presets from a server, since they're partitioned in pages of 40 presets. Those presets are then shown in the presets dropdown. This should hopefully be an easier way to share people's presets. (But not relevant until Simple UI is fixed.)
Used like so: /ut_preset_page 1

/ut_fetch_presets will re-download the presets, but this is mostly a command for mod testing/development.

Fixed a crash (the one that was saying something about pictures).
Last update that added options to stamina shields didn't agree with the Parry Indicator mod, now they are once again compatible.
Added options for teammate player names: font size and opacity.
