Two somewhat experimental changes before I fix bug 89:
1) Don't suspend the LinkCache when including templates;
because we don't call replaceInternalLinks() anymore,
it doesn't do anything.
2) Don't call strip(), removeHTMLcomments(), or replaceVariables()
on template parameters in argSubstitution(). The first two
should already be done on the article including the template,
and the third is unnecessary because it isn't possible to
pass templates as parameters to templates.

These seem to work, but if anybody notices any problems,
please let me know.
