Shades of Mort'ton Temple Building Fixes

[autumn-smellegy]

• Repair action goes from 3t to 4t. It's 4t in both RS3 and OSRS.
• All crafting rolls use the Flamtaer hammer's +40 crafting boost, which matches RS3 and OSRS.
• Success rate of repair action improved based on data gathered from OSRS. The code here was also missing a return, so you could never actually fail the roll and get 0 xp.
• Simplified the resource contribution and xp reward code. Based on observations from RS3/OSRS, the lowest xp drop you can get is always 3, and the highest is (craftinglvl+2)/4, capping at 35 at 99 with flamtaer hammer (effective lvl 139). You can get any amount of xp between the minimum and maximum. Resource contribution is 2x xp, so maximum resource contribution becomes (craftinglvl+2)/2.
• xp awarded is always integer, so I adjusted the formula to multiply by 10 after dividing resource contribution by 2.
• TODO: Shades should be interrupting wall building, requiring the player to click on the wall again. This happens very frequently when solo on RS3/OSRS, and much less frequently with a group. I recall very clearly from rs2 days that it was impossible to build the temple solo, and that is still true in RS3/OSRS. I do not know how to write that code lol
