New Rule: `no-invalid-names`

[bmish]

Disallow unwanted module/test string names.

• No leading/trailing spaces (autofixable)
• No empty strings
• No missing name (ava/test-title)
• No non-string values (numbers, objects, etc)
• No strings starting/ending in qunit delimiters (> or :)
• We could also allow a regexp pattern option to be passed to this rule defining the required format (ava/test-title-format)

A few disallowed examples:

module(' Foo Bar @unit  ', function () {});

test(' it does foo ', function () {});
