Adding Float support to common.utils.Common (might as well do it so we don't cry when we have to make the other client work with this piece of shit)
Adding numSharesOwned, percentOwned and inWatchList to Idea. These are meant to be set ONLY with setters
Changing RMI and Client to add the new fields to the Ideas. Also changed some calls to getIdeaByIID() to be calls to a new function called ideaExists()

(Be wary: I changed the db IP again!)
