Galaxite boulders not highlighted on toggle

[G3sch4n]

When trying to highlight Galaxite boulders on 1.0.0.8 of core keeper, Galaxite boulders do not show up.

Issue is most likely caused by wrong rbg values in tilecolormap.js. Both Galaxite and Solarite have the same values.
Correct Values for Galaxite should be 215, 220, 251 instead of 247, 240, 220

Edit: Fixed with #42
