Converted select element keywords over to using Selenium's Select class.
More select element refactoring applying changes made by Heikki Hakkala.
couple typos; logLevel should be loglevel and locator should be attribute_locator
acceptance test cases for iframes
Removed 'frame' tag when searching for frames, either <frame> or <iframe>,
using _element_find().  Added fix for _page_contains which will search both
<frame> and <iframe> elements. But this fix for _page_contains needs a test
first which is why the fix is currently commented out.
Added tests to verify 'Page Should Contain' keyword works with both frames and iframes. Currently iframe is failing as expected since patch has not been applied.

Added test demonstrating how with the removal of the 'frame' tag from element searches could result in a "NoSuchFrameException" error if multiple elements have the same name attribute.  Also demonstrated is how one can use xpath to search for either frame or iframe or both in such a case as a work around.
Applied fix which allows the internal function _page_conatains to search both <frame> and <iframe> elements.
Added iframe support by removing strict filtering for only <frame> elements.
