Search Plugin
A plugin that adds a "Search" hotkey to some screens (Units, Trade and Stocks)
that allows filtering of the list items by a typed query.
Works by manipulating the vector(s) that the list based viewscreens use to store
their items. When a search is started the plugin saves the original vectors and
with each keystroke creates a new filtered vector off the saves for the screen
to use.
