Add Account choice, Add Folder choice, Add ctime to fname

Not sure if you're interested, but I added the options for users to choose which account and which folder to export. 

Head's up though, there are mods to the convention for file naming (Account:Folder:Creation_Date:Title.html), and the splash screen informational output.

Thanks for making this project, it's great knowing that I can mass-export should I want to stop using Notes.
