Set unknownMimeTypeSupportLevel to zero

See unsupportedMimeTypes below.
Note that unknownMimeTypeSupportLevel (from an earlier design) overlaps
in functionality with the content types (sans subtypes) entries in the
preferred/supported/unsupported mime types below.
This is only because
all of the IANA recognized content type classes are well represented
in the tables below, so very few mime types should end up as "unknown".
Removing content type (sans subtype) entries from the following sets
would force more mime types to become "unknown".
The default value of 1 ranks "unknown" mime types below supported
mime types (levels 2,3,4,5) and preferred mime types (levels 6,7,8,9),
but above unsupported mime types (0 and below).

<property name="unknownMimeTypeSupportLevel" value="1"/>
<!-- These three properties group most known mime types into three broad
classes - preferred, supported, and unsupported.
Connectors may
use this information to optimize their feeds, supplying preferred
formats over simply supported formats (if both are available), and
skipping unsupported formats. The entries of each of these three
classes are a list of content types that may or may not include
subtypes.
Exact (case-insensitive) matches are attempted first.
If a match is not found, a match is attempted using just the base
type without the subtype.
For instance, suppose these properties were as follows:
preferredMimeTypes={} (empty), supportedMimeTypes={"foo/bar"},
unsupportedMimeTypes={"foo", "cat"}.
"Foo/Bar" matches (case-
insensitively) "foo/bar", so it would be considered supported.
"Foo/baz" does not have an exact match, but its content type
(sans subtype) "foo" does have a match in the unsupported table,
so it should be considered unsupported. Similarly, "cat/persian"
would be considered unsupported.
"Xyzzy/bar" lacks an exact
match, and its content type (sans subtype), "xyzzy", is also not
present, so it would be assigned the unknownMimeTypeSupportLevel.
Note that modifying entries in these properties may require
corresponding modifications to the Google Search Appliance Crawl
and Index administration page.
Similarly, modifications to the
Crawl and Index page may also require changes to these entries.
