themes: Move spinifity from the throbgress splash to the two-step splash

At one point in time the two-step splash plugin was forked from the
throbgress splash. Since then the two-step plugin has grown to be more
flexible / configurable.

The two-step plugin is now flexible enough that with the right config
it can mimick the throbgress plugin. Moving the spinifity theme to
use the two-step plugin allows us to remove the throbgress plugin,
removing the code duplication between the 2 plugins.

An added advantage of this is that the two-step plugin has more functionality,
such as capslock indicator support for the password dialog.

Note the throbber-??.png images were modified to add 24 transparant rows at
the top, to get the extra hardcoded throbber-height / 2 space which the
throbgress plugin added between the throbber and the header-image, this
was done automatically using the following command:
convert old.png -background transparent -gravity northwest -splice 0x24 new.png
