Latest homework plus warmups

Latest update includes the following (sorry for the delay):

wk3d2 - Memetube updating - I have a minor issue where blank records are getting displayed in the drop down box at the top of the page, deleted entries see to leave these behind
wk3d3 - Movies - using a database note I have a bug where no movies taken from the database are getting shown
wk3d4 - getting Movies ready for deployment - the only issue here is that erroneous input is not being handled yet
wk3d5 - were we given any homework for this day?
wk4d1 - Mountains app
wk4d2 - Games app done in class (I thought I would submit this as there was no homework assigned)
wk4d3 - Cookbook app (to be completed)
wk4d4 - Project One pitch

I have also added a warmups folder and included all warmup exercises done to date (some may not be complete though).
