check the baseline of Pillar to run a preload for microdown

[Ducasse]

Now that the logic for the unload in the script is correct eg.

#( 'Microdown' 'DocumentBrowser' ) do: [ :name |
		(IceRepository repositoryNamed: name)
			ifNil: [ ('Project not found: ' , name) traceCr ]
			ifNotNil: [ :found |
				found
					unload;
					forget ] ].

we can retry to make the baseline of pillar doing some preloading action before loading the baseline of microdown.
