Text plugin basis with plugin for suggestions/completions. The suggest plugin works for imported global variables, methods, modules and module members. For example typing:

import Blender
from Blender import *
| <- cursor here suggests globals
Blender.Draw.gl| <- cursor here suggests all Draw members starting gl

Currently suggestions are listed in the console when the space is redrawn but will be presented as a menu-style list soon. Also to add are shortcut/activation keys to allow plugins to respond to certain key strokes.
