Fire events as the contents of the tag editor are changing, and listen for those changes somewhere if you want to repond to those changes.

Clean up a lot of old code, bring this component in line with the rest of the codebase. More model binding and less manual data handling. Implement bindings/listeners between the tag editor and the Instance Name(s) input field.

More unneeded code removed, some comments added, trim whitespace from name tag values before save.

Euca 7637 - Give the user the option of adding Name tag(s) directly in the tag editor, and keep a link between it and the Instance name(s) field.
