Make StarDist (and other problematic IJ2 plugins) accessible from IJ1 Macro

[uschmidt83]

As a reaction to PR #6 and reading @ctrueden's comment here, I've decided to make a generic SciJava Command CommandFromMacro that (potentially) allows to call any Command from IJ1 macro (without the need to press OK). The syntax is not ideal, but this is a workaround until the situation has been properly fixed.

Based on @haesleinhuepf's example in #6, I've added a custom macro recorder to take advantage of CommandFromMacro for the two StarDist Commands.

I'm not sure this is the way to go, but it seems to work and is (in my understanding) a fairly general solution that could be implemented/used by other plugins without much effort.

All a plugin has to do is to call CommandFromMacro.record(this, <CommandService instance>); at the end of the run() method to record the macro string in the new format.

For example:

run("Command From Macro", "command=[de.csbdresden.stardist.StarDist2D], args=['input':'Label Image','modelChoice':'Versatile (fluorescent nuclei)','normalizeInput':'true','percentileBottom':'1.0','percentileTop':'99.8','probThresh':'0.5','nmsThresh':'0.4','outputType':'Both','nTiles':'1','excludeBoundary':'2','verbose':'false','showCsbdeepProgress':'false','showProbAndDist':'false','label':''], process=[false]");

Wow, this is so awesome!
