[GM interface improvements] GM input dialogue and Add ship filtering

I wonder if it would be possible to add GM input dialogue. My idea is something along the lines of addGMMessage, where that message will get string from GM (similar to pthon's input() function). For example if I have default values of what radar range will newly spawned ship have, then I could be able to modify it easily from GM interface. I believe this will allow for a lot more options in GM interface through addGMFunction.

Second idea: When spawning ships in GM interface, could we have more filters than just NPC/Player ships? For example by class? Science database has it, but in GM screen I need to remember every ship in the list by heart or skip most of them and just use that few I remember.

Also ship radar icon could be on the ship button for easier orientation in the list. At a first glance I can feel what strength the ship will be (at least if GM is experienced Science station operator). It will really allow for better quick-reactions for player activities in fully GM-ed sessions.

Start by reviewing the GM interface and the proposed addGMMessage and addGMFunction entry points. Define how GM-entered values, ship-class filtering, and radar icons should work, then verify that the interface supports the requested input and ship-list orientation improvements.
