0.5.1: fix UI widget coords — relative not absolute

FTB Library's Widget.setPos(x, y) takes coords RELATIVE to the parent
panel. My code passed (getX() + offset, getY() + offset), so widgets
ended up at panel-pos * 2 + offset, far off-screen to the bottom-right.

Fix: drop getX()/getY() everywhere in alignWidgets. Refresh button,
close button, header bar, sub-panels — all relative now. Plus
BaseBnsScreen.contentTop()/contentBottom() are now plain offsets
(20 and getHeight() - 24) instead of getY()-prefixed.

Visual bug surfaced with user screenshot of HubScreen showing all
buttons stacked on the right edge of the screen with empty dark panel
on the left.
