Add auto complete text edit to Add Food Activity and is able to grab

data from nutrients db and fill them in the various EditText fields. The nutritional data updates themselves when user edits the the serving size. Right now, when the user hit the submit button, the food is saved in the FoodRecordDatabase, which basically keep a record of what foods the user has eaten. And a few changes to other classes and layouts.

HOPEFULLY THIS WON'T BREAK THE PROJECT, PLEASE SAVE YOUR CURRENT PROJECT AND TEST OUT THE CURRENT BUILD. 

P.S. 
Thomas, I un-comment the gender thing in the UserInfoActivity, so just comment it out again when testing the program.
