* CLI refactor with commander
- Modularized the functionality
- All functionality done directly from `./nodebb` now
(still available from `app` for backwards compatibility)
- Moved all CLI code from `./nodebb` to `src/cli`
- Fixed `nodebb.bat` to work from any location, like `./nodebb`, and
also hides command output
- Overwrite some commander methods to add CLI color support
- Added `./nodebb info` for quick info including git hash, NodeBB
version, node version, and some database info
- Refactored `./nodebb reset` to allow multiple resets at once
- Changed `./nodebb restart` to essentially stop and start, as Windows
doesn't support signals
- Added `-l, --log` option which works on `./nodebb start` and `./nodebb
restart` to show logging, like `./nodebb slog`
- Expanded `-d, --dev` option which works on them as well, like
`./nodebb dev`
- Improvements to self-help. `./nodebb build -h` will output all
possible targets
- `./nodebb reset` explains usage better
