sidebar: use a logarithmic tagcloud scaling

Instead of linearly scaling the tagcloud entries based on their counts, scale
it based on the 2 times the natural log of the count.  This gives more weight
to lower count tags, making the whole cloud looking "denser".

theme: turn the shipped theme into a proper theme example

It is silly to ship my blahg's theme with the software.  For a couple of
years, it's been possible to specify the theme directory via the theme-dir
config option so there is no harm generalizing the shipped theme and
encouraging users to copy it and tweak it to taste.

fmt3: remove trailing slashes from generated html

The trailing slashes in some of the tags were a XHTML thing that was
acceptable with HTML 4.  Since both of those are a thing of the past, the w3
validator warns about these slashes.

utils: clear struct tm before calling strptime

Some strptime implementations clear the struct tm while others do not.
Since we want zeros for everything other than the year, month, day, hour,
and minute, we need to explicitly memset the struct.

This wasn't noticed before since illumos libc falls into the category of
zeroes-tm-for-you implementations.

On systems that do not zero struct tm automatically, various random values
end up in tm_sec which causes the subsequent mktime to return a value that
doesn't represent the passed in string's meaning.

static: make URI prefix configurable

This changes the definition of the base-url config knob to be a list instead
of a cons.  The list should have one or two items: the scheme+host+port
portion and the URI prefix portion.  The migration is simple - just replace:

	(base-url . "http://example.com")

With:

	(base-url "http://example.com")

That is, the cons cell turned into a list.

sidebar: make the minimum tagcloud count configurable

Instead of hardcoding the decision that a tag must have at least 2 posts for
