Fix colors of the G-type stars (eg. Sun) #1147

The Problem Even though the Sun is classified as a yellow dwarf (G-type main-sequence). G-type stars actually range in color from white, for more luminous types like the Sun, to only very slightly yellow for the less massive and luminous G-type main-sequence stars. This affects other G-type stars in Celestia too. Notable examples: Alpha Centauri A, 51 Pegasi, Tau Ceti.

Expected behavior All colors to be adjusted based on the temperature, especially for G-type stars. Sun might look like Sirius A.

Celestia has supported blackbody star colors for a very long time. In Celestia 1.6.2, blackbody colors can be enabled by typing %, i.e. Shift+5. In Celestia 1.7.0, blackbody colors are enabled by default.
