Fix some weird problems

[MysteryBlokHed]

One main issue to track things that are very broken.

• [x] Fix output folder When running databind with no arguments, the output folder is created relative to the directory the command was run is as opposed to the root of the project.
• [x] Fix problems with tagging Tags of folders that are not in subfolders have a preceding slash before the function name (eg. namespace:/funcname instead of namespace:funcname)
• [x] Fix while loops breaking .databind files seem to stop being transpiled after a while loop, and the while loop functions are not generated. I'm not sure what's causing this.

It looks like some of these problems aren't actually Linux-exclusive, I just found them while I was testing on Linux. I'm not sure how a lot of them occurred.

I'm not sure how most of these came up. There were never any problems testing on Windows, and it seems like some of the things added in older pull requests (eg. proper output folder running databind with no args in #28) have just stopped functioning.

The issue about Windows while loops using full paths as the subfolder prefix was actually just me having a malformed file structure. It might be worth adding some sort of create-namespace subfunction to databind create to stop people from making the same mistake I did 🙃

Previously, the issue was:

- [ ] Fix while loops breaking
    - [ ] On Windows
          On Windows, the while loops function calls seem to insert the entire path to where
          an mcfunction would be generated?

On Linux, it looks like the tokenizer still thinks that it's in a while loop after the :endwhile. I'm trying to fix this now.

It looks like none of the problems were actually Linux-related, I just found them while testing on Linux.
