Add resource generator plugin

## Command

unthink generate resource my-resource-name

## Arguments

1. Kebab-cased name for the resource. E.g., "hello-world"

## Default Result

By default, the following file(s) will be created from template:

- `src/server/resources/-resource.ts`
- Resource `name` will be set to the match the resource name. E.g., "hello-world" would be `name: "Hello World"`.
- `basePath` will be set to `/`, E.g., `/hello-world`.
- `routes` will contain the following:
- a `view` handler serving up the template
- a `data` handler serving up a JSON endpoint that returns an empty object
- `src/content/templates/.njk`. E.g., "hello-world" would create a template called "hello-world.njk".

By default, the following file(s) will be modified:

- `src/server/resource-definitions.ts` will be modified to include:
- The `import` to the new resource
- The new resource will be added to the `export default` list

## Options

### --view

Use `--view` to provide an alternate name for the nunjucks template

### --no-view

Use `--no-view` to skip generation of a template file and the inclusion of the `view(...)` example in the routes.

### --no-data

Use `--no-data` to skip the inclusion of the JSON `data(...)` endpoint in the routes.

### --base-path

Use `--base-path` to set the `basePath` of the resource.

unthink generate resource hello-world --base-path="/"

### --entry

Use `--entry` to have the nunjucks template include a reference to an entry bundle.

unthink g resource hello-world --entry=hello-world

Would add something like this to the template:
