stinst: Export comments in way they are parsable with pharo 1.4

Add >>#fileOutComment:to: to the FileOutExporter and re-implement it
for Squeak/Pharo to write it as a chunk. This is confirmed working with
Pharo 1.4.

stinst: Put the class variables into the classVars and not the pool

The class variables were placed in the pool and not the class variables
array. This was found while exporting OsmoLogging to Squeak syntax.
