Added default weaponset to frontlib hwconsts
Now the weaponset create function can actually do what it promises and create
a default set instead of an empty one :)
As a special exception, FreeType can also be built with the 'makepp'
build tool, available from http://makepp.sourceforge.net.
Note, however. that you will need at least version 1.19 and pass the
option --norc-substitution to have it work correctly.
