[PEAK] sitemap.xml and unicode module names

playing with simple sitemaps I have found that <import .../> statement
doesn't work in some situations. Try the followin example:

    from peak.api import *
    class Foo (web.Location) : pass

    <location id="root">
        <import module="sitemap_impl" as="impl"/>
        <location id="root_foo" name="foo" class="impl.Foo">
            <view name="index_html" resource="example.res/foo"/>

    from peak.api import *
    root = config.makeRoot()
    sm = root.lookupComponent('ref:sitemap at file:/path/to/sitemap.xml')

Problem is in peak.web.sitemaps.doImport that injects unicode module
name u'sitemap_impl' into sys.modules if module isn't already loaded.
Then lazy import cannot find this module by name and complains
with SystemError('nameless module') in 'reload' on line 195 in
peak.utils.imports. Quick patch for the problem is below. Maybe there
are more places in sitemap.py or templates.py that need some repair.
Inserting 'modname=str(modname)' into lazyModule() itself could be best,
but I am not sure. Althoug it is working too.
