lcd_draw functions

[mrshu]

The NXC API supports drawing some object on the LCD display, such as rectangle, circle and so on (all of them can be found here http://bricxcc.sourceforge.net/nbc/nxcdoc/nxcapi/group___display_module_functions.html).

However, that API is far from being "Pythonic". Also, looking back at http://worrydream.com/LearnableProgramming/#react there is something certainly wrong with RectOut if we can have something like lcd_draw_rectangle.

Also, later on this would mean that having a function lcd_draw("rectangle", ... that would simplify this whole process.

@Adman what do you think?

@Adman so that we can have a good autocomplete.

I mean better:
