Show / hide the search button consistently even fresh after login

[RedAces]

The problem:
the search button (for tracked profession recipes) does not show up for me if I track a new recipe.

It DOES show up if I have a recipe tracked and reload!

Debugging this problem I found that this button should ONLY show up if Auctionator.Config.Options.CRAFTING_INFO_SHOW is set. Some time ago I deactivated this.

This PR fixes the problem that this button shows up on reload (or login) if the config is not set. This makes it consistent to tracking a recipe later!

Additonally I think there are 2 more problems:

• I didnt know that checking the box "Show crafting costs in the crafting view" makes this search button appear. Possible fixes:
  -- Always show the search buttons
  -- Add a new config for this search button with a clear explanation
  -- Change the existing description of the checkbox to include the search button.
• No crafting cost is displayed in my profession window either - maybe CraftSim hides this? The search button is there though...

What do you think for the first problem? I could provide the code if you decide which option you like.
