feat(ngTableSettings): nested options never undefined

This is part of supporting typescript strictNullChecks compiler option

BREAKING CHANGES

`ISettings`: replaced with `Settings` class and a type alias of `SettingsPartial`

`Settings.interceptors`, `Settings.counts`: arrays are cloned therefore any changes to the array will not be recognised

`settings(newSettings)`: any setting value supplied as undefined will now be ignored.

Instead of `undefined` you will need to supply a suitable value as described below:

* `counts` - an empty array to prevent the page size buttons rendering
* `filterOptions.filterDelay` - `0` to remove the debounce delay
* `filterOptions.filterDelayThreshold` - `null` so that a `dataset` of any size will have a `filterDelay` applied
* `groupOptions.sortDirection` - `''` so that grouped columns are NOT sorted by default
* `groupOptions.isExpanded` - `false` so that each grouped set of rows are collapsed by default
* `paginationMaxBlocks`, `paginationMinBlocks` - `0`
