[22205] Ensure the check for IDE stacks is accurate

[livecodepanos]

Closes bug 22205

This patch ensures that user stacks with names similar to the leaf name of IDE library stacks (e.g. "drawing", "diff" etc) are no longer treated as IDE stacks. The check if the stack name is among the lines of revInternal__ListLoadedLibraries() was removed, as all the stacks included in this list either already have their _ideoverride set to true, or begin with "rev". The only exception to this is tsNetLibURL, so for this reason its _ideoverride property is set when this stack is loaded (i.e. in revInternal__LoadIfLibrary)
