Initial revision of beef.dom.createIframe()  Removed 'method' parameter and code path that creates a form and uses created iframe as target.
Revised comments on beef.dom.createIframe() to reflect removal of 'method' parameter & form submitting behavior. Updated existing function calls to beef.dom.createIframe() to remove 'method' parameter.
Clean up .gitignore file.  Accidentally committed changes to it to exclude my Sublime Text 2 project files.
