BF: Ignore spaces when getting variables from name

[TEParsons]

Prevents e.g.

text1 = visual.TextStim(win, ...)
mouse1 = event.Mouse(win, ...)
clickables = environmenttools.getFromNames(" text1", namespace=locals())
for obj in clickables:
    if obj.contains(mouse1):
        continueRoutine = False

from raising a "str has no attribute contains" error
