Update UI and move UI to root path

Updated home.html to allow for easier creation of dialog boxes, created
button to load a local file, load sample file, and load a remote file
via URL. All javascript for UI is location in js/ui-functions.js
Created Settings Dialog box, included plugins

Created the settings dialog box that allows the change of appearance of
Dialog Boxes (more will be added later). Also included the necessary
jquery plugins for the controls to work.
Fixed Issues 1 and 2 (partially)

Added cancel button and close button to LoadRemote Dialog window. The
cancel button brings it back to the WelcomeDialog, and the close button
goes to the ControlDialog. Changed the size of the Settings Dialog not
to take up the entire screen (was never meant to, just forgot to change
it when I commited). I will look into making it window that slide in
from a side.
Added Control Box Button

Added a button to the control box to open the Welcome Dialog to allow
the loading of another file.
