Change RAPID speed_mult to 0.75
Provides a bottom limit of zero to carrying capacity, both weight and storage.
New mod pack - no powered armor.
Rapid speed_mult to 0.5, bash_mult and cut_mult to 0.66

Prevent future crashes similar to ethanol burner one.

Added catch for std::out_of_range in itype::can_use to prevent the
game crashing when attempting to test for an invalid iuse name.

Now it instead prints a debug message and returns that the item
doesn't have that use (and since it's an invalid iuse name, the item
indeed does not have that use!)
Fixes missing entry in blacklist.
