Title: SignEditEvent

This event allows mods to manipulate sign text at edit time. This is useful for serverside mods to define coloured text, censor unacceptable words, etc, like what is possible in ServerChatEvent.

The text field is an array containing the 4 lines of text that should be written to the sign. You'll want to modify this.

The additional parameters are for protection plugins to determine whether the sign should be edited.
