rgb555conv - converts 24 bit color to 15 bit color

I got tired of manually converting 24 bit hex colors (like 0xRRGGBB) into 15 bit BGR555 colors (like 0b0BBBBBGGGGGRRRRR) so I slapped this together to do it for me. Be warned that the 4 character color it outputs is in BGR format for use on the Game Boy Color and the Game Boy Advance instead of RGB. It also outputs a 24 bit representation of the 15 bit color (still in 0xRRGGBB) for use in things like your sprite software.

It outputs a rounded down and rounded up variant, it's up to you to look at it and decide which you like, because they may differ significantly.

compiling:
