Simplify Element and Form inheritance.

[sjohnsonaz]

Each Element and FormElement is unique in what it requires. Account for variables like:

• text
• name
• value

  Element

Element should be a fundamental element. All of its children will all have text and html attributes. Although it may be ultimately confusing, it may make sense to implement every possible fundamental HTML tag. Thus, even if we will implement other classes which use the tag, we will have a fundamental version here.

FormElement

FormElement should be any sort of <input> or similar tag. These will in general all possess a name and value attribute. Some may also have text and html attributes.
