#8 Support for <TEXTAREA>

Current source case options:

case ResponseCode.TAG_INPUT:
case ResponseCode.TAG_SUBMIT:
case ResponseCode.TAG_HIDDEN:
case ResponseCode.TAG_RADIO:
case ResponseCode.TAG_PASSWORD:
case ResponseCode.TAG_CHECKBOX:
case ResponseCode.TAG_OPTION_BEGIN:

Functionality will be good to have something along the
lines of:

case ResponseCode.TEXTAREA:

Search function can search for the "name=" attribute
between the <textarea> and </textarea> tags.
