Change CP level requirement

I suggest to change the CP level requirement from level 75 to level 100 because i think that level 75 is too low and I usually see people getting promoted at level 100+.

Some people can be genuinely fit for chairperson while under level 100. A lot of cases we wait until they are level 100 to promote them but in some cases we do it before because they are clearly fit for chairperson.
