HUD: centre the taskbar, move the portrait/health panel to the right edge

New mods/hud: while a HUD window renders, screen-space vertices passed to
D3D7 DrawPrimitive/DrawIndexedPrimitive are shifted by dx; while it handles
an event, the UI event point (category 5, +0x48) is shifted by -dx. Applied
to cUI_Taskbar2 (centred) and cUI_Mercenary (portrait + health, right edge).
3D belt items line up without help (their projection is screen-centred).
re::AttachRuntimeHook hooks functions only known at runtime (COM methods).
