Spectral

• update pack format to 1.20
• added cherry logs, leaves, planks, fence and (trap)doors
• added bamboo stalks, wood, (mosaic) planks, fence and (trap)doors
• fixed an issue with mossy cobblestone slabs
• added all regular signs (NOT hanging signs. those still need done)

I'm hoping to change my release schedule to smaller, more regular updates rather than bigger ones that are sporadic!

Here's your reminder that there's a Legacy Planks add-on that changes crimson/jungle wood to their former colors!
