themes: default: Use more compact representation of colors.

Regardless of if we use minification of the CSS files, these are beneficial
in any case.

themes: default: Adjust some whitespace.

While more readable, we also may actually save some unnecessary bytes.

themes: default: Remove px from 0px.

This makes the CSS'es work the same, while saving us some bytes (which can
be used for better purposes).

theme: default: Micro-optimize the SVG files.

A lot more can be accomplished if we create groups, which means that a bunch
of the attributes will be shared between elements.

theme: default: Use a more compact copyright statement.

Using the `scour` tool, we may get a lot of savings for the SVG files
(taking care of preserving the IDs, if we intend to manipulate the SVG files
via JavaScript).

httpd-gargoyle: Compare null pointers against NULL.

This way, we get the benefit of some static analysis tools which look for
the semantics of the code.

qos-gargoyle: Remove modification of a function parameter.

The parameter `cc` is not used after a brief check of its value, but we
decrease its value by `hlen`.

Since we are passing cc by value, the changes that we perform inside the
function don't get propagated to the caller, which means that it is totally
useless to make such computation.
