Add `downloadpaste <url> <name>` command
- default to using the filename in the url
- can override name if it is going to overwrite the paste
Add `renamepaste <old> <new>` and `deletepaste <name>` commands
- allows you to rename pastes after you download or want to reorganize
- can delete if needed too
Add `upgrade_looking` and `skin_looking` commands
- same as `upgrade_radius` command but uses the base you are looking at instead of a radius around you
- easier way to upgrades in front of you
- will only search directly attached building blocks, won't handle external TCs
- add `GamePhyics.TraceEntity()` method to handle raycasting entities in editor and ignoring server / client entities
