Text Refactor

[Cullen-Enerdyne]

Can we get better support for textboxes?

This might have to be additional entity that contains text.
In addition to displaying text, the text box should:

• Be resizable
• Support multi-line text, and adjust the line breaks to fit the textbox
• Be movable (this is already done)
• Be editable (we should be able to get a cursor that we can control to edit the text)

Yes the text needs a lot of work... I also want to change how they are rendered, so at some stage I am going to overhaul everything.

Instead of having a bunch of quads with each their own texture we could generate textures with words/sentences, reducing the drawing to one quad, but requires the need to generate textures on the fly. This also means we do not have to change the VAO when updating text, since it will always only be a quad.

Updating text has become significantly cheaper by adding Free Lists in #347.

I might even be cheaper (and simpler) to keep rendering characters separately.
