Restructure project:

The project has grown quite a bit without me remembering
to make any commits...

Here's a summary of what has happened:

- Make the project friendly towards non-flake users
- Add searchers to be created: `nur-package-search`, `nix-lib-search`
- Add misc util scripts for formatting and testing code.
- Split templates into their own directory,
    as they get quite large after a while.

- Add colorized templates.
- Replace some of the xml tags with optionally colorized output.
- Add `--no-color` option
- Add json2nix script, which will convert the json-converted
    nix code back into nix.

Usage:
home-manager-search [ -j | -n ] [-f=<flake-url> [-r=<git-reference>]]
Options:
-h | --help Display this message.
-j | --json Display raw data in json format.
-n | --no-preview Don't display a preview.
-f=* | --flake=* Use a flake url to an instance (e.g. a fork) of home-manager,
generate its options, and use those instead of the global ones.
-r=* | --ref=* If a flake url is specified, this option might be used to choose
a specific reference (branch, tag, commit, etc.) to use for
generating the docs.
Example usage:
home-manager-search
