Render custom templates using deltemplate with variants

This new feature in Soy[1] allows dynamically choosing a variant
template at runtime. Use this in conjunction with reading the config
for a particular request to allow per-request (e.g. per-repo)
templates. Currently only supports the customHeader template, which
uses template.customHeader to specify the variant name.
(Unfortunately like most stuff that is common to all pages, we need
to pass this around manually.)

Since we no longer need to exclude the default custom templates, we
can delete DefaultCustomTemplates.soy.
