This uses hardcoded widths for the main characters used in Minecraft and might not be precise for some characters but better than the previous 15 char hard limit.
Apparently sign colour plugins do not consider &0 to be a colour that
needs to be removed if there is no other code like that on the sign,
thus ChestShop did not register the initial SignChangeEvent, however
after the server software removes the redundant colour from the sign, it
appeared and worked just like a ChestShop one. This commit "fixes" this
by stripping the colour codes from the sign before it is created.
