Word wrap by default

Hi, it would be useful if the little text editor window spawned with word wrap pre-enabled and syntax highlighting disabled, so we don't have to scroll or line break if the note is particularly long.

I've added these lines to annotate_ops.py at line 30:

bpy.context.space_data.show_word_wrap = True
bpy.context.space_data.show_syntax_highlight = False
