Refactor build tasks and config file

Changed:
- Renamed 'mconfig.json' to 'loconfig.json'.
- Renamed 'concat.js' to 'concats.js' to represent flexible functionality.
- loconfig.json: Base paths are nested under "paths".
- loconfig.json: Paths for tasks are nested under "tasks".
- Refactored each task to process corresponding entries under "tasks" in 'loconfig.json'.
- watch.js: Changed concats watch to use task's includes.

Added:
- tiny-glob v0.2.9
- Utility 'glob.js' to use dynamic imports to fetch an available glob function from node modules.
- Utility 'template.js' to provide a function to render template tags (`{% ... %}`) in tasks.
- concats.js: Support for concatenating groupes of files.
- scripts.js: Support for ESBuild's "outdir" option.
