Reimplement the TextField

[marchermans]

The textfield

Current behaviour:

The current textfield tries to behave as the MineCraft textfield on the server side. Which ofcourse fails, since for example the FontRenderer is not available for size calculation.

Expected behaviour:

The textfield to function properly.

Required changes

• [ ] Insert mechanics that allow a control to intercept UI input on the client side.
• [ ] Add networking capability interception to intercept UI input on the client side.
• [ ] Add messages that are send to the Server when the TextField intercepts a UI input and has processed it on the client side with its font renderer.
• [ ] Implement a basic typing supporting TextField. Preferably using some kind of simple background texture.
