TA Text input brick, text should be right aligned (or keep cursor in view)

[garycmartin]

When typing text into a text brick, the text field should be right aligned, instead of centred, to allow you to see what you are typing. Currently, after a couple of words, your input place has drifted off the right of the tile.

The whole of the text input logic needs to be fixed... dead characters are broken, but composite characters work and the running off the end is really bad. But the right justify while typing is a good idea. I should probably expand the size of the brick to fit the text after the typing is finished (or even while it is happening, if I can figure out how) or switch to a left-justified with an ellipsis.
