[0.49.10] Bug: Battle armor weapon static data

[Gribbly1]

Bundled Megamek with MekHQ 0.49.10
Windows 10, Java Version: 11.0.13

It looks like the battle armor David and King David info has been partially overwritten with the Magshot data.

As per 'IntOps: AE' page 46 the David and King David gauss rifles were prototyped in 3058 (FWL), entered full production in 3063 (FWL) and commonly available in 3065.

Additional minor change - the BA Heavy Flamer is listed as 'IS' but should be 'All' or 'IS/Clan'.

[Gribbly1]

David and King David still listed as FS in 19.1, both should be FW for proto and production dates.

I'm going to reopen this issue so @HammerGS knows to review it. It's entirely possible there is a reason behind it being marked as FS, but that's for Hammer to decide.
