[WIP] Table construction overhaul

- Table parts removed completely
- Tables frames are now built using rods or wood (removing the annoying 'attack with rods, make a grille accidentally' issue)
- Add stack to table frame, make table.

**Table types**
*Normal frame attacked by:*
Metal sheet: Normal table
Plasteel sheet: Reinforced table (takes longer to finalize)
Glass sheet: Glass table

*Wooden frame attacked by:*
Wood plank: Wooden table
Carpet tile: Poker table

**Deconstructing**
1) Attack by screwdriver, removes the top from the table, reducing it to a frame
2) Attack frame with wrench, deconstructs frame

*For reinforced tables:*
Must be weakened first with a welding tool before screwdrivering in order to remove the plasteel.
No, nope, nien, het.

You know better than to use istype()! OOP this shit.
