Made 1.9.0 compatible.

Thanks to cbshing pointing out a new on_action code, terraformed planets will now instantly get their textures. Also added a couple for Venus.

Made 1.8.3 compatible.

Made 1.8.2 compatible.

Made 1.8.0 & Synthetic Dawn compatible.

Paradox made a mistake while updating, so this version now supports 1.6.2

Made 1.7.2 compatible. (The patch does nothing to the edited files, so no changes.)

Changing planet classes will now use unique textures rather than randomized ones. See description for details.

Made 1.6.1 compatible.
