Campaign Request - Split Gun Size Research

[Heet]

v1.4:

Research in the campaign currently REQUIRES focus in Big Guns 95% of the time due to the size of that research tree, and the apparent randomness.  You can spend years waiting on a specific gun caliber upgrade (i.e., 16" mk. III) while the research tree happily backfills 9"-11" guns, or 19" mk. I guns which are useless to you.

I've been asking for this for a while, but basically we should split the gun research into more categories, and re-balance the research times for each tech.  The goal being to give the player more direct control over the research path they want to take.  For example, if you want to focus on heavy cruisers, you research medium caliber guns.  You can CHOOSE to push for super battleships, or completely ignore them.

Small: 2 to 6 inch guns

Medium: 7 to 11 inch guns

Large: 12 to 16 inch guns

Super: 17 to 20 inch guns, only accessible once 16" mk II are researched.
