Subject: GUI: Fix scrollbars

- removed +1px in ListWidget, added in lordhoto's 2007 commit 68eb28a
(aka r29971 in svn) `Fix for bug #1670082 "GUI: Modern theme gfx glitch
in launcher".`, because it made clip this last line of scrollbar in all
themes, which doesn't look good. In 2007 theme was written in .ini,
which is not the case now. I don't see any glitches after removing this
"fix";

- fixed how scrollbar top and bottom scroll buttons are drawn in
ThemeEngine::drawScrollbar: there were these weird magic numbers, but in
reality extra space that buttons should occupy is hardcoded in
scrollbar.cpp (ScrollBarWidget) and is just +1px.
