Move the scripts I commonly use into Nix files managed by Home Manager. Some, like `mounter` and `unmounter` are desktop-only, but this can be addressed in a future commit to create per-host scripts or desktop/non-desktop scripts. This commit also removes a number of unused scripts that are either included in packages like `git-extras` or aren't used.
