Option for Icon Selector to filter by type

[mrvn]

TL;DR

The icon selector when changing a station name should allow filtering for items or recipies.

What ?

I suggest adding toggle buttons to show items, recipies and virtual signals or a pull down menu to select the type of icons shown so the list of icons to choose from can be reduced to manageble levels.

Why ?

Currently one can select icons from items or recipies but they are all mixed together. One can search by name but that's not always helpful. With some of the larger mods like Angels or Bobs the volume of icons gets impressively large.
