Fish Minimum needs to adjust as Rod Level increases

[TheIncredible]

or maybe introduce a guild building....similar to how the stable works...so giving a benefit every 5 levels:
level 05: minimum fishlevel 2
level 10: minimum fishlevel 3
level 15: minimum fishlevel 4
level 20: minimum fishlevel 5
level 25: minimum fishlevel 6
level 30: minimum fishlevel 7

no idea what the other effect would be (+x% something.....rarity/quality/chance for higher fish/fishing energy regenartion).....thinking about it a little more i think chance for higher quality fish is missing in the lab upgrades
