Make the UTF-8 BOM optional for file encoding

Currently you can set the encoding type for SQL files to Unicode (UTF-8) and when you do so the files saved in the Editor are UTF-8 encoded, and a with a byte order mark (BOM) is added at the beginning of the file. Please add an option for saving files with UTF-8 encoding but no BOM. The Unicode specification does not require a BOM and it interferes with a number of applications that do not expect a BOM. http://www.unicode.org/faq/utf_bom.html
