Bug 1349178 Make nsIEditor.transactionManager readonly r=m_kato

Browse Source 
There are no app which replaces transaction manager of editor.  Additionally, replacing transaction manager of an editor with different editor or same editor but after initialized again due to some reasons may cause unexpected problems.

Therefore, this patch makes it readonly.
