Autocomplete added to Rental Form

Hey

Everything needed for the autocomplete ajax to work are done in the
external files and all included in this update in the 'ac' folder in
assets

There is still one detail that I am working on, currently there are two
places that we need to enter the db info, password, and db name and I
am trying to make it so it reads from only one, the original config
file database.php.

For now go into assets/ac/demo/ and change the config.php to your
settings, sorry for the inconvenience will fix it soon I think.

I wanted to upload it so you guys get it quicker and then I will make
the change sooner or later when I figure it out
