Patch v0.23.16

Here is a small patch with a bunch of fixed bugs that were found by our community. Since most of them were pretty critical, I've switched from v0.24 development to fix them all.

v0.23.16 release notes

Features:

🔸 added craft validation and cleanup on load, wich will be able to fix and load broken spacecrafts with missing attachments, parts, etc.; 🔸 added "clear" command to console.

Changes:

🔸 changed all pivot position of command modules and probe cores to the bottom socket; 🔸 thermodynamics calculations deltaTime now clamped to 2 days / sec max, otherwise it becomes very unstable and parts start exploding; 🔸 further reduced thermal production coefficient on some engines; 🔸 slightly reduced collision radius for dynamic attachments so small parts like rcs mounting point now can fit rcs engines without problems.

Fixes:

🔸 NaN temperature on crafts where some parts were placed inside the payload fairing after fairings were installed; 🔸 NaN temperature after decoupling part of the craft and then time warping (in case you switch to decoupled craft); 🔸 last time warp button with time warp 1 month / sec sets warp to 7 days /sec; 🔸 missing burn time values for some Hydrolox engines; 🔸 "Rumble" and "Hose" decouplers stay coupled after separation if they were attached using second radial attachment pivot point; 🔸 symmetry stops working when RCS block was mounted longitudinally and other parts attached to it. 🔸 reentry and mach effect suddenly disappears sometimes; 🔸 heat shield stops protecting rocket parts after undocking; 🔸 wrong position of center of thrust and lift if you move craft to the side and then attach engine / wing; 🔸 crash when loading any mod then returning to main menu and then continuing the game; 🔸 improve memory consumption and performance in some cases.
