[PATCH 5/4] ui-{tree,repolist}: improve button spacing for browsers w/o CSS

[Eric Wong]

For browsers on low-end machines running browsers without CSS
support, the default tree view displayed "logplain" when it
should be "log plain".  Stop relying on CSS and add a space
in between elements to improve accessibility.
