[why] The octicons got a lot updates. But they do not have a font anymore. [how] Keep our old codepoints constant, but add the new icons thereafter. This commit just moves all the mechanics in and moves the (old) font. No actual update here. The mapping file has been created with the analyze_octicons script. Fixes: #490 Signed-off-by: Fini Jastrow <[email protected]>
