Version 1.3.13c

- Advanced Railgun Accelerator and Launcher were using the wrong amounts of energy per shot by mistake. This has now been fixed (bugfix).
- Advanced Railgun damage increased by 20% (to compensate for the bugfix and make the damage more in line with the cannons).
- Tweaked the sulfur powered hyperdrive to function more properly.
- Made some improvements to the standard asteroid icons containing the modded resources when in creative mode.
