Merge pull request #1 from jfirebaugh/iD

Update iD URL
Merge pull request #3 from steventlamb/master

Add zoom threshold, alternate widget type, unit tests, more examples and rework source code
Fix path in examples
Use iD and JOSM as default editors
Update unittest related to default editors (oops)
Now the var is "editors", not "overrideDefaultEditors"
Test editInOSMOptions before including control

We need to be able to include the files AND to not display the control,
for example to include it programmatically after some action.
