Tools: replace 'Command-Line Tools' + misc updates

Replaced 'Command-Line Tools' folder of modding tools for 'Multipurpose Plugin Utilities, and added `#Command-line-tools` tag.

Reasons:
- Command-line tool describes type of user interface for a tool, e.g., GUI tool vs command-line tool, but it doesn't describe their purpose (which can vary wildly). This is more useful as a Tag instead of a folder.
- TESTool, a common modding tool, did not neatly fit into any other category.

Multipurpose Plugin Utilities now hosts:
- Tes3cmd
- TESTool
- tes3lint
- also includes backlinks to Wrye Mash and DeltaPlugin as related tools.

---

Populated stubs:
- 'merge_kf'
- meshoptimizer_bindings
- TESTool

Moved:
- Tes3conv to Version Control Software
- Esp-QuickEditor to Low Level Editors

Added:
- tes3lint
