Gets or sets options for various asset types.

@see lithium\util\Text::insert()
@param string $type The name of the asset type, i.e. `'js'` or `'css'`.
@param array $options If registering a new asset type or modifying an existing asset type,
contains settings for the asset type, where the available keys are as follows:
- `'suffix'`: The standard suffix for this content type, with leading dot ('.') if
applicable.
- `'filter'`: An array of key/value pairs representing simple string replacements to
be done on a path once it is generated.
- `'paths'`: An array of key/value pairs where the keys are `Text::insert()`
compatible paths, and the values are array lists of keys to be inserted into the
path string.
@return array If `$type` is empty, an associative array of all registered types and all
associated options is returned. If `$type` is a string and `$options` is empty,
returns an associative array with the options for `$type`. If `$type` and `$options`
are both non-empty, returns `null`.
