build 0.5.2 — Once Upon The Universe Steam update #1328986

Gravity Well no longer prevents selecting stars when clicking directly on them while the power is armed. Gravity Well channeling now hides the mouse cursor while the casting animation is active. Tutorial popups now appear after a short delay, giving important events a moment to register before guidance interrupts the action. The first biosphere tutorial now begins only after a sector has reached sufficient metallicity for biosphere formation. Stars now use animated visual frames while preserving their existing mass-based sizing. Fixed a rare tutorial soft-lock where the first rocky planet could lose its parent star before the Stellar Stabilization tutorial appeared.
