Remove the need to have 1 unspent regular skillpoint for weapon set skillpoint allocation

Tried to use the weapon set skillpoint allocation, and immediately ran into the following issue - by default the weapon set skillpoint allocation is completely disabled, even if you have lots of unspent weapon set skillpoints!

You need to unspec 1 regular skillpoint, and only then the weapon set skillpoint allocation starts working, and you can allocate uny number of them up to the max limit of free points you have left.

I don't see any need for this.

As long as you have unspent weapon set skillpoints, they should be available for allocation at any time!

There is no need for this "to use the system at all you need 1 unspent regular skillpoint" thing.
Its extremely unintuitive and unneeded limitation, and might be the reason why many players don't even utilise the weapon set skillpoint allocation system at all.
