Schemas cleanup: Handle IntNodes properly

IntNodes were getting caught by the StandardAnalyzer for small
values. This could probably be avoided by using whoosh.fields.INT
in the schema declaration as well (and that should get done
eventually). However, a SimpleAnalyzer as the default is better for
l2cs' case anyway, because the CloudSearch server will handle
stop words and query optimizations.

Additionally, IntNodes are now properly generating unicode
elements.
