Text field

[reubenberghan]

This input accepts text from the user. It does not handle special characters (that's the rich text field).

• By default it should accept an unlimited amount of text, with a configurable limit
• By default, enter will submit, but can be configured to be a line break instead.
• By default, alt-enter does nothing, but can be configured to be a line break.
• Size will be configurable
• The field should be fixed size by default, but it can be configured to grow with the input.
• Should accept an onChange parameter and update every time it changes with name, value and (configurable) validity.
• Should accept a validator prop that returns true or false.
