Split/Merge editor

Assets can only be bought/sold as a whole. Unfortunately, more often than not, stock needs to be sold off partially. This is when the Split/Merge editor is needed.

Splitting stock simply removes units from an existing asset and creates a new and similar one with them. Merging stock combines similar assets. Care should be taken here as the merged stock is basically destroyed.

Two assets are considered to be similar if they have the same name, variant, cost, returns and state of ownership.
