Fix for fall of the samurai (boshin) shrine building global buffs.

The original charge bonuses for traditional and were not being applied correctly based on caste category (ie. traditional, modern), no idea why. But as a easyfix I changed the effects from:

> Shrine level 1 gives global +5 charge to traditional units
> Shrine level 2 gives global +10 charge to traditional units
> Shrine level 3 gives global +10 charge to ALL units

to the following:

> Shrine level 1 gives global +3 charge to all units
> Shrine level 2 gives global +6 charge to all units
> Shrine level 3 gives global +9 charge to all units

updated the description

> armourer and gunsmith whilst not buildable got same effects as previous building for old savefiles.
> fixed accuracy bonuses for Artillery_foot and infantry_line. Big credit for identifying the missing mod entries @Commisar Jon Fuklaw

> changed way buildings are disabled so they don't show up on tech tree UI incorrectly.

>increased mod compatibility (now works with my Pike&Shot mod)

>Updated to work for rise of the samurai
>possible fix for FotS accuracy buffs
>description updated to describe state of mod for RotS and FotS campaigns

Extended functionality to fall of samurai campaign with following changes (please test):
> Shrine level 1 gives global +5 charge to traditional units
> Shrine level 2 gives global +10 charge to traditional units
> Shrine level 3 gives global +10 charge to ALL units
> Blacksmith level 1 gives global +1 armour and +4 accuracy to all units
> Blacksmith level 2 gives global +1 armour and +8 accuracy to all units
> Blacksmith level 3 no longer exists
> Training camp no longer exists
