Bug 1343037 part 12. Implement nsTextEditorState::SetSelectionStart. r=ehsan

Browse Source 
This introduces three behavior changes:

1)  Before this change, in cached mode, we did not enforce the "start <= end"
    invariant.
2)  Before this change, in cached mode, we did not fire "select" events on
    selectionStart changes.
3)  Changes the IDL type of HTMLInputElement's selectionStart attribute to
    "unsigned long" to match the spec and HTMLTextareaElement.
