+Eeschema, libedit: fixed last problems when editing alias info.
+    Now alias changes can be undone, and are correctly updated in lib
+    when updating the current edited component in memory
+    New code could be a good starting point to store all aliases info in the
+    root component,
+    and also easily store it to the *.lib files and remove the .dcm associated files
+    (most of code is done)
+
