Add some improvements from 1.03

[Leseratte10]

Would it be possible to port some of the bugfixes of 1.03 back to this 1.02 source code?

For example, the following two bugs (which are probably already fixed in 1.03)

• Friend room race random track selection forces random for the whole GP
• Track selection does not "keep" selected track, but always jumps to the last played track
• Create a lap count & speed mod patch for CTGP1.02
