(Finally) JSON Object Created,

Input constraints improved, some confirmation dialogs added

Phillip, I have tried to tidy the thing up a bit. But dont worry,
basically you just need to focus on line 195 of Main.js. In that line,
the JSON Reminder object is retrieved after all the inputs are
collected.
Now I think the next is copying that info into the local database. Then,
we can work on the thread to read that local database to prompt
notifications.

I will try to be in tomorrow to give you a hand mate!
