fixing bugs

Hi,
i've found errors in points costs of SM dedicated transports (Rhino and
Razorback):

Is:
- Storm bolter 10 pts
- Extra Armour  15 pts

Should be:
- Storm bolter 5 pts
- Extra Armour  10 pts

Codex: Space Marines page 159

And this spelling error:
Space Marines -> HQ ->
Is: Labrarian
should be: Librarian

Thanks for this epic tool :)
