Update Statements added to Java Developer Tools

I just now added support for update statements in the Excel to SQL module. I also optimized both insert and update statement otput generation to greatly increase calculation times (10,000 records in a fraction of a second on my macbook). I also added a pre-built jar file to the build directory so it doesn't have to be built from source. Here is a link to the Jar file
