Add support for loconfig.local.json

[mcaskill]

Added:

• Utility config.js to merge loconfig.json (indexed) and loconfig.local.json (ignored).

Changed:

• Utility template.js to process any template tags (in a string) in objects and arrays.
  • Added new default function resolve<T>(input: T, data?: object): T to process objects and arrays.
  • Renamed function template() to resolveValue(input: string, data?: object): string.
• Script watch.js to support customizing the development server (BrowserSync) from loconfig.json.
  • Switched to BrowserSync's recommended post-2.0.0 syntax.
  • Organized logic into functions for easier reading.

Example:

// loconfig.json
{
    "paths": {
        "url": "acme.test",
        "src": "./assets",
        "dest": "./www",
        "images": {/* … */},
        "styles": {/* … */},
        "scripts": {/* … */},
        "svgs": {/* … */},
        "views": {/* … */}
    },
    "tasks": {
    }
}

// loconfig.local.json
{
    "paths": {
        "url": "dev.acme.test"
    },
    "server": {
        "open": true,
        "https": {
            "key": "~/.config/valet/Certificates/{% paths.url %}.key",
            "cert": "~/.config/valet/Certificates/{% paths.url %}.crt"
        }
    }
}
