Revised and New Tools

I managed to revise the Sub2/Owner Carry Financing Tool to allow for multiple loans (and to fix some nasty Javascript bugs). I also created a suite of Amortization Tools. You can usually find similar tools on the web somewhere, but I seem to always need them and forget where to find them. This way I will always have a link. I've never found a web-based calculator that finds the interest rate or term, so these are handy additions. Try 'em out!
