Improve xp gain for trucking

[Dirty Mike]

I have been trucking for a little while and really think that the xp should be increased for the skill.

at level 0-15 your only option is taking building materials, with the usually highest xp being 100 per run averaging around 13-15 min round trip. to get to level 15 (15,000)xp you looking at roughly 37 hours of driving the same one of 2 routes to the construction sites. that seems a little excessive where 37 hours put into mining for example would probably have you around level 60

reduce loading down to 10sec would be fair,
