[fixed] experience gains from reading science book

intel_exp gain from reading science book decreased the higher Sveta's intelligence was; this is a relic of the old experience system
increased intel_exp gain to 4 for 1 hour of activity (ie.equivalent to 1 hour of tier1 exercise; arguably should be higher due to risk of damage to sight and associated expenses)

exp gains from $downlibrary['BookStudy'] should be adjusted as well, but that's a little above my level of expertise
