Subject: [PATCH] Sorttable: avoid registering init multiple times

The script pre-dates jQuery usage so it's understandable the amount of
workarounds and boilerplate that were needed back then to run code at startup.
They are not necessary anymore and this commit removes them which also avoids to
register extra listeners to run the init callback.
