Shield rebalancing attempt (#408)

basic shield balancing attempt.
Legion shield given 45 damage limit, along with giving it some energy resist instead of 0 still a low amount set to 30, 
Made scrapshield the craftable shield a weaker version of the legion shield with a damage limit of 45 and also increased both shields to have the same ballistic modifier as the stopsign shield with a +5 bonus to bullet resist.

Shields still have a measly 2.5 stamina efficieny modifer and a low integrity so they will crumble under fire or stam crit the user using them so this is just a minor change to the legion and scrap shield to be able to block up to rifle caliber rounds without them completely bypassing the block.
