Removed test code in create API example.

The following code was returning a null pointer

Element videodockModule = getElementWithAttribute(firstChild, "name", "VideodockModule");
Removing the lines solves the issue and does not load the videodockModule. This issue could have been introduced with a change to the xml client file.

This closes #2713

Fixed typo for English 106.

The old browserid.org URLs are deprecated and will stop working at some point.

Slight refactoring of getJoinURLwithDynamicConfigXML() to make consistent with other functions in bbb_api.jsp
