* Validate Post Item in Convert-Online.php
* Correct Samples - Currency, Accounting, and Downloader
* Smarter Color Formatting for Currency
* Use helper->log Rather than echo in Convert-Online
Responding to comment from @PowerKiki about use of echo for error messages. I do not believe that an exception is warranted, but other scripts use helper->log for error messages, and now so will this one.
The samples have become unwieldy when running them from a browser. In particular, the drop-down lists are fixed size with no scrolling, and many of them are now just too large. I have moved all the Calculation samples up a level, and broken several categories (Basic, Chart, DateTime, Engineering, Financial, and Reader) into several pieces.
Convert-Online (now found in the Engineering category) had a number of different problems which are now resolved. It is the only member with any significant code change.
