id-length rule should be able to ignore JSX intrinsic elements

Currently, every exception for the `id-length` rule must be passed explicitly as a string. My proposal would be to allow exceptions based on their kind, not only the literal value.

As mentioned in #40, one possible improvement to the rule configuration would be to allow all type parameters to be excluded from checking. It seems like intrinsic elements would be a welcome addition, given the amount of HTML tags otherwise provided manually.

An example configuration object might look like this:

```json
{
"id-length": [
true,
{
"min": 2,
"max": 10,
"exceptions": ["_"],
"check-type-parameters": false,
"check-jsx-intrinsic-elements": false
}
]
}
```
