DEMO: practical IAT

- scoring script included (good) but requires command line (bad).
TEST: add a non-travis test for key-RT

- currently fails on mac when run on local machine; test is skipped on travis with py.test test_misc/test_event.py
TEST: more permissive time range was needed
TEST: skip test isPressedIn -- can't set mouse pos yet
BF: builder movie component: correct indentation
ENH: Updated MovieStim2.py demo

- uses .mov included in folder.
- looping is turned off, as it stalls this video at end and does not
loop ( user can press q to quit if they do enable looping).
- not fixing looping right now as this is the only video I have tested
where the looping fails (I have only tested 10 videos though).
- if becomes a big issue will spend more time to fix.
