web: use subset font for dartboard numbers

glyphs.

Also removing the name table from the icons font to further reduce size.

+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide

+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded,
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
